Toyota - Corolla :: 2005 XRS - Shuddering When Accelerating At Highway Speeds
I have a 2005 Toyota Corolla XRS with a manual transmission which has developed a shudder. When this shudder started, it only occurred when accelerating at highway speeds, or maintaining highway speeds. Now it happens at lower speeds if I give it gas without downshifting, but at reasonable RPM, 3000-5000. I cannot feel the shudder in the steering wheel, but the whole car shakes, and it definitely feels like it is coming from the front end. I have had the tires balanced and rotated. I also have replaced the IACV and MAF due to a CEL. These were replaced after the shudder started. For a few days after the replacement, the CEL returned, but now I am no longer getting it.
There are no visibly obvious issues with the suspension or the drive shafts or CV joints, and the motor mounts likewise look okay. I am not getting a CEL of any kind, and I replaced my plugs 6 months ago, but I pulled them anyway, and they are not fouled. I don’t think the issue is in my suspension, steering, or wheels because I cannot feel it in the steering wheel. I don’t think my half shafts are warped because the shudder happens at varying speeds, and the instant I let off of the gas, it stops. Though this doesn’t rule them out completely, there is no clicking from the CV joints. When I brake, the car slows smoothly, so the rotors are fine. I have run injector cleaner a couple of times, and octane boost once. These both seemed to solve the issue, but did not make it stop, and it has gotten worse lately. My wife did put low-octane gas in the car once, but it was weeks ago.
Honda - Cr-v :: 2005 Started Shuddering When Accelerating From A Stop
My 2005 Honda CRV (92,000 miles) recently started shuddering when accelerating from a stop. I took it in to have the front struts replaced (back were done about a year ago) and get it aligned. Was told I needed a new CV axel. All that got changed, but shudder wasn't better. Took it back & was told steering was loose (car was pulling to the right after the alignment) and all was good. Not the case.
Took it back and was told I needed the other front CV axel replaced. Still not better. Had all 4 tires replaced (it was time). Still not better. As a side note (might be relevant...I don't know) my transmission had to be completely replaced/overhauled in Dec 2014. Was told someone had put in the wrong transmission fluid and there were metal shavings throughout. So in just over 6 months I've put close to $5000 into my ten year old, paid off car (nothing but normal maintenance until now).
Why it is still shuddering/vibrating? Reading on here, I'm supposed to make sure the wheel lug nuts are tight, but anything else I can check? Again, don't know if this might be relevant, but the car spent its first five years in a cold climate (Germany) and has since been in South Florida.
Ford F-150 (2004-2008) :: 2005 - Occasional Bucking / Shuddering When Slow Down From Highway Speed To About 30mph
I have a new to me 2005 F150 SuperCab Lariat 4x4 with 155,000 miles on it. About a week ago I replaced the from passenger hub assembly and half shaft (torn boot). When doing that, I noticed that the IWE actuator was not working right (would not compress evenly). When taking that off, there was a bunch of rust that came out of the vacuum line ports. It started moving freely after cleaning all of that out that I could (I will be replacing it soon). I assembled everything back together and all seemed OK mechanically.
I also scanned the truck and saw the code for a bad IWE solenoid so that is being replaced tonight. I also have not checked the drivers side yet.
So...now that I have done all of that, the truck started occasionally bucking/shuddering when I slow down from highway speed to about 30mph and lightly accelerate again. It does not do it every time though. There is no grinding/whining noises either. Could this be caused by the IWE system somehow? Maybe slowing losing vacuum and having one engage and the other disengaged?
Ford 6.0L Power Stroke Diesel :: 2005 Excursion Started Vibrating When Getting On The Highway
So, on my way home from checking out a house all of a sudden the truck started vibrating when getting on the highway. Then it got worse quickly. So I pulled off at the next exit and pulled into a parking lot, the truck shuddering badly any time I pressed the fuel pedal. Had it towed to my local Ford dealer. I'm thinking torque converter/transmission, but I freely admit I don't know. Here's what I think is pertinent info-
1. I bought it at 84k miles, now 122k. Oil changed every 5k, fuel filters every 10k, coolant every 20k, trans fluid every 20k. Don't kmow what was done first 84k miles before I bought it.
2. Driveshaft rebuilt one year ago. Both fr and rr diff fluids changed a few months ago, along with transfer case fluid.
3. When in park or neutral engine revs perfectly smooth. When placed in gear and fuel is added it starts to shudder, getting worse as revs go up. Does not vary with road speed, only with engine speed and load into transmission.
4. There are no codes at all. All temps were normal. Engine oil and trans fluid level normal.
5. A few months ago when coming home from a trip I suddenly had the same symptoms about 3 miles from home, but not as bad as today. Made it home taking it easy and went to bed. I was exhausted from a long day of driving and when I test drove the truck the next morning to check it out it was smooth as could be, so I thought maybe I imagined it. Symptoms did not reappear until today, a few months and several thousand miles later.
Saab - 9-3 :: Engine Suddenly Shut Down When Going 65 - 70 MPH On Highway
I was going 65-70MPH on the highway and the engine suddenly shut down. I pulled over on the shoulder and tried to restart but the engine would start for a second then dies again. I tried several times but it would not start. Waited 10 min and tried again with no luck. I called a towing service and a friend to pick me up. The towing guy called me 40 min later and said the car starts fine. I have driven it for couple days since and tried to recreate the problem (warming the engine, accelerating hard to 5000 RPM, stop and go situation) but the car runs great. No problem whatsoever with power or jittering or unstable idle or starting the car.I talked to 2 mechanics and they both think it is the fuel pump failing. But I am not convinced since I could smell gasoline when I was trying to start it.I have no check engine light on and I checked for recorded codes with my BT OBDII tool – nothing.
Do you think it might be CPS? Wouldn’t I get check engine light on if it is CPS?
Saab - 9-5 :: Battery Light Suddenly Started Flashing
The battery light (but not the ! warning light) suddenly started flashing a week ago, and then a day later the car wouldn't start so I took it in for repair. Was told the battery needed to be replaced, but that it was drained because the alternator was defective. So both replaced. Within one day of driving it home, the battery and various other lights started flashing anew (which had happened last after it was jumped and while I was driving it into the mechanic the first time). Car then went dead again after turning off ignition. Wouldn't start.What's wrong with the car? BTW, mechanic has car (which we towed in) and now can't get problem to recur despite his having driven it around several times, for shorter and longer trips! My sixth sense tells me as soon as I pick the car up and drive home, I'll get the loss of battery/power experience and it going dead yet again! He says he checked for short wires and belt issues.

I just purchased a used 2006 package 3 with 66500 miles on it. Drove it to work today and the car started sputtering/shuddering when i was accelerating onto the highway. The check engine line came on so I took it to the dealership. Turns out it was a bad sensor.
When they fixed the bad sensor, the mechanic told me that its normal to feel a slight stuttering when the gas engine kicks in or off which seems to be confirmed by other members here.
Ford F-150 (2004-2008) :: Shuddering On The Highway Under Light Load / Misfire On 7
I have a 2005 f150 4x4 with a 5.4 it was studdering on the highway under light load, i changed the plugs and coils it worked great for a day now working worse and giving a misfire #7, so i swapped the injectors around still misfire #7.
View 8 RepliesFord F-150 - 1997-2003 :: 2000 - Bouncing / Shuddering On Highway - Cylinder 5 Misfire
I have a 2000 f150 5.4 liter engine. I traveled about a month ago and while on the highway it started "bouncing/shuttering" really bad. I pulled off and while still in drive but completely stopped it was still bouncing but when in park it stopped. I took in into the Ford dealership and they said that cylinder 5 was misfiring and it was losing pressure fast. Then it stopped acting up completely and they couldn't find anything wrong with it.
Well about a week ago it started bouncing again on city roads (no highway). The check engine light came on and Orielys said it was a cylinder 5 misfire. Also, under the oil cap and in the tube where you would put the oil in has a yellow thick substance on it. I know that it is water in the oil. Also, there is a black "gunk" not far from where you would put the oil in. Could these problems be connected?
Passat (B6) :: CEL Blinking And Car Started Shuddering After Tank Filled Up
So I filled up my tank tonight and started off home when the car started shuddering, not bad but shuddering and the CEL came on and blinked so I pulled over and shut the car off, waited a minute or two then turned it on, everything was fine and after a little longer the CEL turned off but turned back on again after 30 or so miles. The car is still running fine.
Do you think its the evap emissions valve? My wife said it shuddered a little when she filled up last week as well. Or it might be the coils? I have a warranty so its going in tomorrow anyway but I am going to drive it to work and drop it off.
Subaru - Outback :: 2006 - Started Shuddering At Idle
I have a 2006 Outback XT, which recently started shuddering (like it wants to stall) at idle... At least that's how it started. I noticed it for a few weeks but with no check-engine light, and no error codes cropping up, I kind of ignored it. It then started to stall at idle. Took it to my local guy, who checked all the simple stuff: vacuum hoses, mass air flow sensor, he even removed and cleaned up the throttle body. But the problem persists.
I guess the part that really has me puzzled is the lack of a check-engine light or an error code. With how computer-regulated cars are nowadays, I'm baffled as to how this isn't causing some alarm to go off.
Toyota - Corolla :: 1995 - Started Shuddering While Going Up Hills?
95 corolla 277k miles. 4 hours into a long trip went over a huge bump and the shocks seemed to "bottom out". Like they compressed as much as they could. Pulled over half hour later for a break.
After that drove rest of way home. Car started shuddering and slowing down going up a hill. Had to floor it just to get it to be 60 mph. Hill wasn't that steep. Seemed to do ok on flat parts.
Was a little low on gas so pulled over to fill up. Noticed car idled very roughly felt like it was going to stall while pulling into gas station.
Gas cap was a little loose. Didn't hear the whoosh of the vacuum you usually hear when undoing the gas cap either.
After that it seemed to be a little better going up hills. I drove it home, and a day later drove it and it seemed to go up hills ok.
It still idles very weirdly, roughly and like it's about to stall. While driving it sounds ok.
I was thinking fuel pump but now i'm not sure. It might be related to the gas cap, maybe the bump loosened it.
Golf - Volkswagen - Misfire :: 2003 - Engine Started Shuddering?
My engine started shuddering rather considerably a few days ago, seems to be misfiring. Happens both while idling and accelerating. Thought it could be a bad spark plug, and was prepared to replace them. Which is doable, but not easy, considering they're not very accessible with this particular engine. But when I lifted the plastic cover off the engine to take a look, I noticed this tube (circled in picture) had been worn away considerably in one spot. In fact, it's barely attached.
Now I'm no expert, but I've read that a leaking or disconnected vacuum hose can cause exactly the type of issue I'm experiencing. I'm wondering if the object pictured is in fact a vacuum tube. Might that be the issue? If so, how easy would it be to repair it myself? I'm not very experienced with making my own repairs, but I'm good with a set of tools, as long as I have instructions.
Ford F-150 (2009-2014) :: 2012 - Missing / Shuddering On The Highway Between 1200 - 1700 RPMs During Slow Acceleration
I have a 2012 4x4 EB CC. In 6th gear, on the highway between 1200-1700 RPM's, during a slow acceleration, it feels like it is missing or shuddering. It is most pronounced going up a hill, and/or towing something. As soon as you get above about 1700, it goes away. Rig needs to be fully warmed up (not just the engine, but tranny/drivetrain). Needless to say, this is generally from about 52-65 mph, which is most highway (not freeway) driving I do. At times it's so bad my wife says it's time to get a Chebby.
Had it in about a year ago, couldn't duplicate it. Took it in this last week. Did the TSB on the plugs, and was told that would fix it. It didn't. Took it back in; they couldn't duplicate the issue. Rotated the tires hoping that might do something. Took the head service guy for a ride, and made it happen; it was very obvious then. It seems like the tachometer should bounce or shudder a bit when it's doing it, but nothing. It's going back in on Monday to see what they can do.
Golf IV / Jetta IV :: 1995 Volkswagen Started Bucking And Shuddering Suddenly
I'm a broke grad student with a 1995 Jetta. I've had it about four years, and it's mostly been all right. Granted, it's mostly held together with luck at this point--my dad's a former mechanic, and he did a fair bit of work on it before I moved a thousand miles away. The other day on my way to work, the car started bucking and shuddering, especially when I first started moving. I was very nearly out of gas, and I thought that might be the problem. I put some in and things got almost totally better almost immediately. Tonight, the car tries to start, but it won't catch. My dad thinks I have water in my tank. Would that do this?
View 5 RepliesSaab - 9-2x :: 2005 - Misfiring On Cylinders 2 And 4
My 9-2 is misfiring on cylinders 2 and 4. At first we suspected a timing issue but that doesn't appear to be the case. My mechanic is looking at it but can't seem to locate the problem... so far:
- replaced old spark plugs
- checked the coils (moved them to see if the misfiring followed the coils--it did not)
- checked the timing belt (all good)
- compression is good
- fuel coming in is rich
He's dropping the exhaust today to check things from that end... A faulty mass airflow sensor wouldn't effect specific cylinders would it? and we'd see a degradation in the fuel richness right?
Saab - 9-5 :: 2005 - Shuts Off While Idling At Red Sign
2005 Saab 9-5 ARC 2.3T67,000 Miles
Noticed a problem 2 weeks ago with my little Swedish meatball while at a red light on the way home. While idling, the car just shut off. I'm assuming it was a stall, but the car did not sputter and it was idling at around 900-1k RPMs but then just cut out. I put the car in park, and it started right up without issue and I drove the rest of the way home with it running fine. A couple days later, the same exact thing happened.
I took it in to my local Saab shop for a radiator hose replacement and an oil change. I told him about the stall/cut out problem, so he hooked up the Tech II but could not find any trouble codes. So he did a software update to the computer and told me to monitor it and call him if it happens again.
After getting my car back, it ran fine for a few days. I tried to get it to stall again by just letting it run in idle for 10-15 minutes but it wouldn't cut out. One night, I went to the gym for about an hour and came out and my car started right up and I drove about 5 minutes and came to a light. Car cut out again. However this time, it did not start up again. The engine would crank, the computer would go through the checks and give me the Check OK but it just wouldn't turn over. I tried to start it 5 or 6 times but no luck. I got out and pushed it to the side of the road. After about 2 minutes for sitting there, I tried it again and it turned over. Started right up like nothing ever happened.
The car drove again fine for a few days and then yesterday it cut out again. Same thing. Car would crank but not turn over. I let it sit there for 2 minutes (as traffic was going around me at a red light ) and then tried it again. The engine turned over but it did not start up fine. It definitely stuttered as it was trying to start and I had to give it some gas to get it running smoothly.
Couple of observations: This has only happened while idling (in Park or Drive)This has only happened when the car was warm. I've never had an issue starting in the morning or before the car warms upThis appears to only occur when it has been warm outside. (We've had a few days in the 60s here in PA)The Check Engine Light has never come on. So no trouble codes have ever been logged.
I've been searching the forums and most people seem to recommend replacing the Crank Position Sensor (my mechanic wants to do this as well). However from what I understand, if it was the CPS the car wouldn't stutter like it did when starting after a stall and wouldn't the CPS cut off the engine while driving as well?
Saab - 9.3 :: 2005 - No Heat / Fan Blows But Cold Air
My daughter has complained about periods of no heat- fan blows but cold air. Next time the heater works fine. She is keeping coolant level up but does need to add a bit (pint or so) say every other month. Last week during the Chicago snow storm she called and told me the heater (which had been working) blew a bunch of "smoke" into the car and onto the windshield and windows which then froze solid. I assume the smoke meant steam and she did say it had a sweet smell when I asked her.
Car was towed to a SAAB dealer who ran the car for a couple hours and found no issue and then drove the car for a period with no issue. I had my local mechanic also check it in the past for no heat and it also worked fine then. Only thing I can think of is that there might be a small/intermittent leak in the head gasket with an exhaust bubble forced into the cooling system? That does not explain the steam in the passenger compartment though. Could it?
Santa FE SM (2001-06) :: Sudden Clunk Then Power Loss And Car Started Shuddering - Throttle Body Or MAF?
I was driving down the road and the car was driving great. all of the sudden I heard a clunk and the car lost power and started shuddering. I made it home and cut the car off. When I start it now, the car runs rough and stalls out. I can't get it to a place to check the codes so I am trying to self diagnose. I was thinking it might be the MAF so I took it out and cleaned it well. there is still no change in the way the car runs. it seems like the fuel isn't getting to the engine as I put my foot on the gas pedal it stalls out. I'm not too excited about buying a throttle body if it's the MAF. It could possibly be something else.
