Oldsmobile - Cutlass :: 1991 / Surge Feeling And Does Not Want To Idle When Warmed Up
91 olds cutlas supreme with about 70,000 miles has a miss - when cold runs fine warms up then does not want to idle and has a surge feeling but at highway speed do not notice it. Plugs are clean, spark wires changed 8,000 miles back . Could it be a coil pack failing?
View 6 RepliesMitsubishi - Mirage :: 1991 Won't Start After Being Warmed Up
This car has the 1.5 liter 12 valve motor and a five speed transmission. Ran pretty good until a few days ago when it died. the next day it started up and ran ok for about a half a block and then I had to pump the gas to keep it running. I had bought gas at a dinky budget station that I had never been to before so I suspected bad gas and I put in a new fuel filter which did not work. I then put some Seafoam additive in. After I got it started I revved it up a bit to try and clear things out and then let it idle for an hour or so.
The engine smoothed right out and didn't idle rough but did not start after I turned it off. I pulled a plug wire, put in a bolt and tested for spark against the valve cover. Not even a weak spark, nothing. I looked for the coil but there is no coil and I am told that the coil is in the distributor. I also saw a reference online about the crankshaft sensor possibly being the culprit. What a crankshaft sensor looks like and the engine compartment is so crowded with hoses, wires and all kinds of things it is real hard to see anything from above.
I am wondering if the coil is bad do you have to get a whole distributor ( I was quoted a price of $269 for a new one) or can you take it out of the distributor and replace just the coil.I have a brand new 154 piece Craftsman tool kit, but I am 62 years old and back when I learned how to work on cars it was a lot simpler. Now when I open a hood about half the stuff there is unfamiliar to me. My other vehicle (Chevy C20 van) is not running that great and gets awful gas mileage. The battery is new and I have never ran out of gas with this car, so they are not suspect.
Mitsubishi - Mirage :: 1991 Will Not Start Again After Warming Up
91 Mirage starts and runs ok but usually will not start again after warming up. What are the possible causes and how do I check to eliminate dead end cures.
View 3 RepliesEclipse - Mitsubishi :: 1991 - Periodically Bucks And Surges Especially When Going Uphill
My wife has a Mitsubishi 91 Eclipse with an with a 1.8 liter engine and automatic that periodically bucks and surges, especially noticeable under load like going uphill but can occur during straight line highway driving. After doing a complete tuneup, changing the throttle position sensor, O2 sensor, having both the ecu and tcu rebuilt, check all vacuum lines, replaced ignition wires, replaced fuel pressure regulator and checking fuel pressure, replaced injectors,checking all electrical sensors and connections, etc. etc. I, nor professional mechanics, cannot determine what may be causing this condition. At this point I'm thinking either the fuel tank needs removal and cleaning or its the fuel pump, coil, ignition switch, or torque converter. Here's a clue... I'm finding an oily substance on the pavement that appears to be coming from the transmission area. It doesn't appear to be ATF nor oil. I'm suspecting the torque converter is leaking.

I have a 91 Mitsubishi gto TT. I love my car and i was really hoping to repaint it soon but this problem is becoming more apparent. My car runs fine for the first 15 minutes, runs like a beauty! but then once it is warmed up it starts to struggle. I cant accelerate hard because it hesitates alot. The problem im having is pin pointing the problem. Ive searched a lot of stuff on the web and some people have similar problems.
Could it be bad spark plugs and wires causing some cylinders not to run properly? If so then why does does it run fine for the first 10-15 minutes?
I'll probably have my plugs and wires changed to see if that changes anything.
I just dont understand why my car accelerates great when cold but when hot starts to run sluggish.
GTI 337/20th Anniversary :: Car Surge From 1500 Rpms To Around 750
So my 20th AE has been wrecked. But here is the issue, the car will idle for a about 30 seconds to a minute but surge from 1500 rpms to around 750. But after that, it won't idle. If I let it sit for a couple of days, then it will idle for a little bit then die again.
View 2 RepliesGolf VI R :: When Idling RPMS Would Surge Ever So Slightly
I've been dealing with this for some time now because it hasn't seemed to affect my performance when I am getting on it, but when I am at idle the rpms will surge ever so slightly and i can watch the needle on my boost gauge bouncing up and down. i have a WINtake on the car and it started ever since i installed that. I am wondering what this could be. I've already taken the whole intake out and reinstalled thinking i had a leak somewhere. even tried swapping my maf with a known good one off the lot on a brand new R.
I read somewhere that someone had their maf in backwards. could this be the issue? I don't have any power loss that I am aware of. in fact, if its down on power now, i would have a hard time believing that it could be much faster with what i have done to it. this idle surge will get worse when i have my ac on also. someone make me realize that I am missing something stupid and simple here so i can have a normal idle again. I am half tempted to put my stock intake back on to see but i no longer have the turbo inlet plastic pipe to test it with.
Santa Fe (CM - 2007-12) :: Surge Only At Idle Speeds About 200 Rpms
I have a 2008 Hyundai Santa Fe. Has about 65k miles on it and has regular maintenance and tune ups when needed. It is cared for. The last tune up was about 2k miles ago. Spark plug change, oil change, filters, etc.
I have noticed lately that when the car is moving at idle speeds, it will surge about 200 rpms. It does not happen when the breaks are on or stopped or in park, or moving at higher speeds. It only does it while moving and with no acceleration. It happens in Drive and Reverse.
I live in the city of Lima Peru so a 4x4 is useful but it also requires some tight parking but when it starts to surge, it is a huge pain.
C/K :: 1998 - RPMs Will Surge By About 500 - 600 While Driving At Constant Speed
A few days ago my 98 C1500 started having what I can only imagine is some type of torque converter issue. While driving at a constant speed the RPM will surge by about 500-600. This surge does not coincide with any type of acceleration, it's more like the converter is letting go and the RPM's just rise and fall back down. The fluctuations also seem to stop after about 15 minutes of normal driving. I have had no real noticeable transmission issues. At first i assumed it was my tranny fluid just breaking down so to get me home I used a bottle of Lucas.
The bottle seemed to do the trick for only a couple of days and now the problem is back...no better, no worse. The only difference I have noticed is that before the addition of the Lucas my fluid looked perfect and now it seems there is a bit of varnish. No smell, nothing seems burnt, just a little dirty. I haven't changed the tranny fluid for about 70k and the truck now has roughly 160K on it. My concern is that if I do change it the transmission will crap completely and I'll be on the hook for a rebuild.

Chevrolet - Blazer :: RPMs Surge High At Startup, Then Dies
I have a 1998 Chevy Blazer (2WD) with 115k miles. When I turn the key and start the car, the RPMs rev up really high for about 4 seconds and then drop down real low until the car dies. All in all this is about an 8-second process, and it sounds like I'm flooring the accelerator when, in fact, I'm not even touching it. The Blazer just started doing this, but previously for about the last few months about once a month, when I would start the car I would get a loud backfire sound which sounded like it came from under the hood (driver's side), and this was followed by the smell of exhaust coming into the cab through the AC vents. How to go about diagnosing this since I'm unable to drive it to get the codes read
View 11 RepliesSanta FE SM (2001-06) :: 2004 - RPMs Running High / Car Seems To Surge
2004 Santa fe. Having issues with RPM running high. When car is started, RPM sits at 1500 for a few mins, then drops to 500. Seems to be having issues either getting into gear or staying. At any mph, car seems to surge and not feel like it's getting either gas or power. While on cruise at 55+ mph, car will also surge with RPM dropping 500, then kicking back in. This goes on every few seconds up to random times.
Had it looked at this past weekend at a dealer, and of course it didn't do it one time, after doing it for a half hour prior on the interstate. Tech found no error codes when he checked it as well. Car was fine for an additional 300 miles, then it started again out of the blue. Pulled out at a red light and I though I was going to stall.
Just got laid off so I'm trying to eliminate before putting a lot of money into it if I don't have to. 132,000 miles.
Ford - Thunderbird :: 1994 - RPMs Surge While Cruising Down Freeway Intermittently?
My car (1994 TBird, LX) has an intermittent problem where the rpm's surge while I'm cruising down the freeway. I've noticed that it happens more often on an incline, and it also happens more during rush hour when I have to frequently slow down and the accelerate again.
If I had to guess, I think it's the TCC Solenoid that's the issue. Would replacing this likely solve the problem? Or would I be better served having my mechanic unplug it? My car is giving error codes to replace the camshaft position sensor (related?), and while important, I need to address the rpm issue first as it's getting progressively worse. Tranny fluid is clean, although I've only owned the car for 2 months so I don't know when it was last replaced.
I can't afford a huge repair, but I have a certified mechanic who's always done right by me, but he's not the best at diagnosis. I'd feel better if I could whittle down the issues and then just tell him what to fix.
Ford F-150 - 1997-2003 :: Engine Will Surge Up And Down 2 - 300 RPMs For About 10 Seconds When Cold
I have a 2002 F150 5.4 2 valve. only when the engine is cold, everyone once in a while the engine will surge up and down about 2-300 RPMs for about 10 seconds. also right when I put it in drive it will surge. I was thinking about pulling off the trottle body and cleaning it.
View 3 Replies3000GT/Stealth :: Extremely High Idle - Surge Between 1300 And 1800 RPMs
So I had this issue with my idling at 1300 rpms but every now and then it would idle at 400 and barley run then one day it didnt want to idle at all so I checked the iac and it was bad so I changed my oil, fuel filter, iac, cleaned my throttle body, fixed a vacuum hose, and cleaned my air filter.
When I started it it idle at 2200 I drove it a little and it dropped down to 1300 the next day I started it and it idled at 800 and staid there for four days now it idles at 2000 then will drop down and surge between 1300 and 1800.
I read that the oil you apply to the filter can contaminate the Maf and you should clean it but a lot of people said the one on a vr4 can't be cleaned while others say it fine. Is there a way to check the maf?
Elantra XD (2001-06) :: 2005 - Loss Of Power On Acceleration / RPMs Surge Up Very Slowly
So my 2005 elantra 2.0 CVVT has 189k on it 1 owner.
I got a check engine light one day and i read the code. Came out to be 02 sensor code bank 1. So i order a denso o2 sensor and replace the part.
I drive the car for about 400 miles to reset monitors and get a check engine light. P0420 cat code. At this point the car drives with normal power and pickup.
1000 miles later my car has lost power. It doesn't have any get up or power when driving normally. I take the car to my local shop and they recommend replacing front cat. I replace front cat, same issue.
At this point i'm not sure if it is a transmission problem or maybe my 2nd cat or something else?
On the freeway if I put my pedal to the ground the rpms surge up very very slowly,
Also seems like the car doesn't shift till around 4k rpms, seems like previously it shifted sooner.
Ford Super Duty (1999-2016) :: F250 - RPMs Surge When Let Off The Gas While Driving
I've got a 99 f250 5.4 that runs like a top. In the last 6 months I've been chasing a little problem. It doesn't happen all the time but seem to be happen more and more. While driving any speed If I let off the gas the RPM's hold at around 1500 then surges down to 1000 then back up again to 1500.
Does that 2 to 4 times then all good. Give it gas again it does it again. It kind of does it when it wants. Could be fine for a trip around then next trip it acts up again. Checked a lot of the vacuum lines, PVC valve and replaced the idle control next to the EGR valve. EGR is next.
Idles and runs fine except the surge thing..
P0401 code as well.
Mitsubishi - Galant :: Revving Engine / RPMs Started To Pulse Up And Down
On my way to the grocery store my car's RPMs started to pulse up and down (between 1 and 2) when driving. While stopped at the red light it would vibrate very hard. When i put it in park the RPMs would rise fast before i shut it off. It did the same things on the way back home plus the check engine light came on. A few hours later i put a little oil in it and drove it around my neighborhood and it didn't do any of the things it did that morning.
View 5 RepliesFord 7.3L Power Stroke (1999-2003) :: Idle Surge When Tuned / RPMs Drop To Around 621 - 630 Then Shoot Back Up To 660 - 675
Recently I have noticed that when on a tune other than stock I am getting a surge at idle - my RPMs drop to around 621-630 then shoot back up to 660-675. On my stock tune my RPMs stay around 640-667 and don't cause the surge (felt as a shimmy so to speak). Is there anything else that causes a similar symptom? I attribute it to tuning due to it only happening when running anything but stock but could be wrong.
