Ford 6.0L Power Stroke Diesel :: Intermittent Bucking / Hesitation Up Hills - No EGR
When I am on the highway, my 2005 Excursion (6.0) will hesitate/sputter/buck intermittently, usually between 70-80mph/ 1800-2200 RPM, but especially triggered by hills and inclines. Each sputtering episode usually lasts about 5-10 seconds and then will go away for minutes at a time. Does not sputter upon take off or initial acceleration. There is no smoke of any kind. Just got it out of the shop where the mechanic replaced ALL 8 injectors and the fuel pump, as well as flushed the fuel lines, and new fuel filters, and oil change (2 injectors were bad, but there was metal in the fuel filters, so to be safe I replaced all of them - ALL OEM PARTS for everything, including filters).
The week before, I had the IPR valve replaced. Also, recently had the back pressure sensor replaced and the EGR was deleted - and turbo cleaned when the EGR was deleted last month. I also tried unplugging the ICP sensor to make sure that wasn't the issue. Dropped $6k into this thing in the past month and about to lose my mind (and wallet). All research points to either clogged EGR or bad fuel injectors, but both have been addressed, so I am not sure where to look next. No current codes showing up. No signs of leaking oil.
Prius (2004-09) :: 2007 - Intermittent Sound While Driving?
I am a relatively new owner of a 2007 Prius and am curious about a sound I hear quite often while driving.
The sound is similar to a cd changer changing disks my package doesn't have the disk changer). It seems to happen when braking but I haven't pinned it down to one catalyst.
It seems to be a normal sound and I am not worried about it since riding in my roommates '07 Prius and heard the same sound.
Ford 6.7L Power Stroke Diesel :: Intermittent Transmission Shifting Stutter When Truck Is Cold
For those of you tuned and deleted......intermittent transmission shifting stutter is gone now? Mine sure is. Never once since the mods have I had that annoying stutter when the truck is cold and I'm easy on throttle between 2nd and 3rd gears. What a relief it is to have it shift NORMAL ALL THE TIME!!! Stutter no more after H&S Tune and Delete, for about two months now.

My 2010 Santa Fe has an intermittent all window condensation problem, regardless whether the car has been idle overnight or whilst driving it has occurred on numerous occasions. In one case in the morning I had to use a towel to dry the inside windows. I have tried leaving the heater / AC on various settings but it still occurs. I have noticed that the door windows when I open / close them the seals do not touch the glass. In the short term the AC and fast windscreen/rear window buttons do clear the moisture but it does re-occur especially whilst driving...
View 6 RepliesPassat - Volkswagen :: 2004 - Intermittent Squeal While Driving
For several months, my 2004 VW Passat (1.8L Turbo FWD) has been making an intermittent squeal while driving. The noise is brief (lasting usually a fraction of a second), is loud, screechy and high-pitched (like a belt slipping), sounds as if it's originating from the rear passenger's-side area, and always occurs just after I begin to drive after being stopped at a light or stop sign. It occurs most frequently when I make a left turn (never a right turn) and sometimes when proceeding without a turn. When it's heard while driving straight, it's accompanied by a momentary hesitation in speed, but whether this is just engine hesitation or active deceleration I cannot tell. The problem began in the fall of 2011, stopped during the cooler months (I live in southwest Florida), and began again once ambient temperatures climbed again into the 80's. It usually occurs once or twice per day (but some days not at all) and typically in the afternoons when the air temperatures are warmer. I never hear it when the brakes are applied, and the brakes do not squeal. The noise is not accompanied by any dashboard warning lights.
My local VW dealership claimed that the cause was rusty rotors (as I had recently moved to FL from New England), and I spent several hundred dollars having the rotors replaced, only to have the problem reoccur as I was leaving the dealership's parking lot. I now have an independent mechanic who has been road-testing the car for several days and has heard the squeal once but is puzzled as to its cause. There is no uneven brake wear to suggest that the calipers are being applied unevenly. About 2 months ago, when the squealing noise was absent in the winter months, my mechanic removed a 6mm piece of aggregate which had become lodged beneath the vacuum plate of the rear driver's-side brake assembly. However, a month later, the squeal returned as before. My mechanic is truly puzzled and at this time can only suggest having the rear brakes and calipers replaced.

View 5 RepliesDodge - Caravan :: 2007 - Intermittent Vibration Which Feels Similar To Driving Over Rumble Bars
Our 2007 Grand Caravan with a 3.3 Liter Engine has intermittent vibration which feels similar to driving over rumble bars. It usually occurs between 30-50 mph but sometimes at 70-80 mph as well. Have had the suspension checked and had outer tie rod end replaced. Also had sway bar bushings replaced and front end aligned. We then brought it to transmission shop and had a transmission diagnostic performed. They found no faults with the transmission and thought the engine needed a tune-up which we did with no success. At a recent oil change, we asked for them to test drive it and check again for any suspension problems. They did not notice any vibration during the test drive and found no problems with the suspension.
View 4 RepliesGrand AM :: Stutter When Driving And Go Up A Hill
Ok, when I'm driving and go up a hill or have to give it light pedal it stutters, almost like a cyl drop. I'm pretty sure its not a cylinder drop. It will continue to do it until I release throttle and mash it down again.
Also, when i turn the key at start up, I get nothing. I have to put it in N then it starts right up. Neutral saftey switch? And would that be related to the above issue? Guy at a shop said he thinks its IAC and said its connected to N switch?
Golf/GTI VI :: Engine Bucking While Driving At About 40 Mph
So, this past Saturday, I was driving down the road at about 40mph when all of a sudden, the engine started to buck and violently shake the car. I immediately pull off the road and settled on a side street with engine still bucking. When I made the turn, I applied a bit of throttle to get it round and there was essentially no throttle, so I kind of coasted to a stop. It was the strangest thing. I let it sit for 10, turned the key, and the starter turned the engine over only to start bucking again. Immediately turned off the car.
Figured I'd program the car back to stock mode (have APR Stg 1 flash) and give it a shot. Except this time, the starter worked and the engine didn't turn over. Tried a few more time, but got the same result. Starter worked, engine didn't. Fast forward an hour and a half and a flatbed shows up to haul me to the dealer. Called the dealer today to find out they haven't been able to replicate the issue and there's no code. In fact, they actually got it to start and it's been idling for 30 mins. When the tow guy came out, he thought it might have been an issue with the car not getting fuel - which seemed like a possibility. But, the car has a full take of 93 oct in it.
Like I said, APR Stg 1 ecu flash and that's it. Has 31K mi. DSG. Funny thing was, a day before this all happened, I brought it in for a 30K check-up and there weren't any issues.

View 5 RepliesElantra XD (2001-06) :: Frequently Jerk Or Stutter While Driving
I just bought a 2001 elantra. The car frequently will jerk or stutter while driving like the gas is bad or it is starved for something. When the stutter problem happens while driving the check engine light flashes but does not stay on. It usually only stutter 1 time but has as much as 3. The other day when I was in a drive thru waiting to order the car kinda sputtered during an idle then shut off the check engine light did not flash at this time. It restarted fine after that.
I pulled the codes and read them and I have 2. I am not sure if they are related to this problem. They were U0D00 and P0705. For the P0705 I cleaned the terminal but did not pull the negative on the battery the reset the computer. I reset the codes and the problem still is happening but no new codes are present. The code P0705 has not returned since.

Phaeton :: Stutter Or Brief Jerk While Driving / Coolant Level Warning
While driving my 04 w12 a few months ago i noticed a "stutter" or brief jerk while driving. the next morning i had a "coolant level" warning. i took the car to a mechanic i use who diagnosed the problem as a broken coolant line involving the transmission cooler, with the result that coolant migrated to the atf. indication was that the tranny was toast, along with the atf cooler. I authorized a repair (not inexpensive), keeping costs down by installing a used tranny. since the car was "fixed" i still got a "jerk" usually in fourth gear, sometimes in third. i took the car back and was told that the tranny was flushed numerous times and the transmission was reflashed. i picked the car up yesterday, but i still get the "jerks", now usually in third gear.

I have a 2002 camry with 212000 miles on it and just lately when driving at a constant speed 60 mph or over it starts to buck or jerk a little bit and you can feel it in the seat. I've had the throttle body cleaned and put in a new mass air flow sensor and it hasn't fixed it yet. What might be causing this? It doesn't do it when accelerating or slowing down.
View 9 RepliesGolf/GTI VII :: 2015 - Bucking For About 5 To 10 Seconds When Driving After Filling Tank
I have driven my brand new 2015 GTI SE manual almost 5 months and have odometer reading 1800 miles. I am pleased with the performance and handling of the car, however experiencing the following issue---- after filling my tank with gas, I have noticed that my car "bucks" for about 5-10 seconds after driving down the road from the gas station. I have also had this "bucking" problem 2 days after fill-up. At first, I thought it was bad gas, but I used 4 different gas stations with the same results. Since the problem is intermittent, I have tried to just tolerate it, and to see if it would go away as the car gets broken in. However, this problem has continued since my first fill-up. The VW dealer service advisor says they can run my car's computer to look for fault codes, but he does know of any tech bulletins on this problem.

View 16 RepliesPassat (B5) :: Stutter On Acceleration
I'm trying to fix a B5 1.8t Passat, it is usually a pretty quick car but recently it has had an issue where it "stutters" when accelerating. Meaning, if you put your foot down, it doesn't "take off" right away (you can't get the wheels to squeal) (not that I would try to do that normally). I know how the car used to feel, so it's not turbo lag or the ABS kicking in. It seems to behave normally after the initial stutter, it's most noticeable in 1st gear. I replaced the gas and air filters for fun, but no dice. No codes on VCDS shareware.
I can think of a few theories based on searches, but am not sure how to proceed;
- Plugged cat: expensive, not sure how to diagnose positively to avoid throwing money.
- Turbo issue? Wanted to hook up a gauge to see if the turbo is boosting correctly. Need to find a place to plug in.
- Clutch? Unlikely as the RPMs don't jump, and in third it doesn't slip. The acceleration makes it feel like something is slipping though
- ABS misbehaving? Light isn't showing up though.
Ford - F150 :: 1995 - Engine Gives A Bucking Kind Of Sensation When Driving Around 40 - 45 Mph
I have the above vechicle with a straight six engine and with 100,000+ miles and have a problem that has been ongoing for sometime and am totally confused as to what to do. The pickup starts great in the morning and idles fine. No roughness during accelleration or anything while idling. I take my daughter to the bus stop and seems to be running fine. When I drop her off and drive for a short while the engine gives a bucking kind of sensation. This happens at the low end of the "Normal" range of the temperature gauge and apparent when driving around 40 - 45 mph. I think that it may slightly be running a bit rough at freeway speeds but I cannot for sure tell (Idaho roads are not the smoothest. ha). When the engine gets warmer it doesn't seem to be happening.
What could be causing this? I gave it a tune up before (OEM plugs, wires, rotor, cap) and it still happend. I made sure everything was even Motorcraft to see if that had anything to do with it! My nephew replaced the hoses at the top of the engine (I think they are return hoses) because they were bad but still having problems.
Ford F-150 - 1997-2003 :: 5.4L Engine Stutter While Turning - Misfire At Idle Or While Driving
My 2003 f150 5.4l has developed a slight stutter when I turn from a stop or go from reverse to drive or vise versa. I had thought it was the IAC so I replaced it but the issue is still there. There are no engine codes and it does not miss fire at idle or while driving. The problem appears to be happening only when the a/c is on. Could the belt be the cause?
