Passat (B5) :: Loss Of Power As Accelerating And Downshifting
Air blowing noise that sounds like a disconnected turbo or hose. Loss of power accelerating and downshifting.
View 4 RepliesPassat - Volkswagen :: 1997 - Feels Like Downshifting Even When Not Accelerating?
When I'm driving, steady mph, my car feels as if I've just downshifted, or that my foot slipped off the gas pedal. When this happens I've noticed that the tachometer drops down from say 20 - 30 to 10 or less! But just momentarily. It happens to a warm or cold engine. It's going to give me a whiplash! I've brought it to my VW dealer. They put it on the computer, and no problem comes up! No lights on my dashboard are on either. This problem is really annoying.
View 3 RepliesTouareg :: Transmission Malfunction - Jerks When Downshifting
VW replaced my entire transmission and it still jerks into gear when downshifting to a stop or hitting the gas hard while coasting!
Also, I swear there is now binding while turning a la moteur stepper. New tranny. New rear drive shaft. Allegedly new transfer case (I cannot confirm this though). New new new programming. And still the darned thing vibrates by butt with a downshift that a Bettle with 300,000 miles on the clock would not dare make.
Any reference to the operation of the transmission and the sequencing of the various clutches and other coupling devices with respect to gear selection and engine conditions?
Sonata NF (2006-10) :: Transmission Jerks When Downshifting (intermittent)
My daughter has a 2010 Sonata with a 4 cylinder and an automatic transmission. She is pretty frustrated with an intermittent problem. Every once in awhile, especially if the engine is cold, the car jerks while slowing down. She believes it is the transmission when it down shifts. I have driven the car and have not been able to duplicate the problem myself. The dealer recently changed the mapping for the transmission in hopes that would work but it hasn't. The dealer hasn't been able to duplicate the condition either.

I have a 1999 Jeep Cherokee Sport v6. I have replaced the fuel pump, fuel filter, Battery, cables, alternator, distributor cab, and plugs and my car keeps stalling out on me. It drives and idles just fine but when I am driving or accelerating the vehicle dies, I let up off the gas and it restarts itself. When I hook it up it does not read an error code!! Not sure what to do next.

I have a 2011 Susuki 250 that I am no longer driving because it jerks and lunges as if it is stalling. It takes about 15 minutes before it starts stalling lunging in equal time of it running ok. The F1 light goes on at the same time as it stalls. The stall cycles are about 3-5 seconds with the same amount of time running. I'v had it at the mechanics for WAY too long. He has transferred new parts onto my bike from another new one with no success.

My '99 Passat (1.8t) shakes and jerks violently during acceleration. If the terrain is smooth & flat I don't seem to have a problem. The problem gets pretty extreme during acceleration especially if going uphill. Also, it seems as if it really kicks in when the transmission shifts gears. I have replaced the fuel filter, dump valve, & all 5 mounts to include the front snub mount.

Like the title says my truck has been stalling while driving. Accelerating or cruising it dies for a second, two at the most, and then just keeps chugging along again.
I thought i'd fixed the problem last year when I did injector O-rings and 50 cented my UVCH. It hadn't done it since, until two days ago. Started out with a two good solid stalls while gently accelerating up hill. I had thought maybe my fuel pickup foot had finely given up the ghost because I was below a quarter tank. But I filled her up full, and then she did it again about 50 miles of driving later.
I didn't catch the first four stalls on my torque app, because I'd just recently decided to stop logging every trip, with the thinking that it had been half a year problem free, why keep logging waiting for something that isn't going to happen. I did catch the 5th stall on the torque log. But I'm having trouble trying to figure out where it happened in a 30 min log.
First question where would yall start in tracking this thing down? Next what data actually should be logged? I think I've got some extra stuff in my logs that isn't necessary, and is maybe bogging down the system. I get one data point per second resolution on my logs. Are there ways to improve the resolution, will getting rid of some PIDs work?
Lastly I need to attack this thing smartly, without throwing time and money at unneeded parts. I had surgery and I've been out of work for 3 months and I'm looking at another 6 before I'm making money again, and there is no unemployment for the self employed. Also I only get 3-4 light weight upright hours a day to work, exceed that and I'm back on the couch battling swelling for a week.
Also is there anything I can do while driving to "flag" the stalls so I can find them more easily in the logs?
Golf IV R32 :: FX850 - Clutch Sticking / Rapid Jerks Which Leads To Stalling
So I've been dealing with this for a little while now and it's starting to really irritate me. With my 850, when cold, it drives awesome- perfect engagement, pressure, etc. When hot, I'm noticing that even with the pedal to the floor while in gear, I might get a few 'jerks' until it frees up. Also engaging while hot (in traffic) can sometimes cause rapid 'jerks' which leads to stalling, the pedal engagement is all over the place and you really have to know how to drive the car, just to get it right.
Now I've bled the line about 4 times now in the last three years and it seems to improve slightly (maybe placebo effect), but I'm not looking into it maybe being the grease on the input shaft? I know we greased the throwout bearing and input shaft, but it was a very light coating since I was nervous about getting grease on a $2400 clutch.
Camry 2012+ :: 2014.5 LE Hesitate When Accelerating Then Jerks
I bought New Camry 2014.5 LE. Most of time, my wife drives for short commutes to train stations and work. Its been 1.5 year and it still has less than $10K miles.
I feel it hesitates when I push the accelerator all the way quickly, then jerks. The engine revs up the moment I step on the accelerator but it hesitates before it actually picks up speed. If I step on the gas gradually, its fine.
I have Rav4 (4 Cyc) which does not behave this way.
I took the dealership and asked about it. The tech says it is drive by wire system so unlike old cars, which respond very quickly, may hesitate and considered normal. Some online article says the car's software learns a driving habit so it depends on the driver too but many other postings also suggest its a software glitch.
Is it really normal, a feature of 6 speed or is there a technical service bulletin addressing this issue so that I can show to the tech? Eco mode is turned off.
Lexus GS 2006-11 :: Jerks At 60 Mph When Accelerating From Full Stop
When I accelerate from full stop with 3/4 throttle when car gets to 60-70 mph it stops accelerating for 1 or 2 sec, there is is also a little jerk. After that it continues to accelerate normally. The problem is not present if for instance we drive 30 mph and then use 3/4 or full throttle. I talked to dealer and they said there might be a little jerk but nothing more, and it might be solved by software update. In my opinion its definitely not a slightly jerk, car completely stops to accelerate for a moment. Car has about 45 k miles so its almost like new.

Hyundai - Accent :: 2007 - Occasionally Jerks Upon Accelerating
My 2007 Hyundai Accent Automatic has been, what I'd call jerking, off and on when I go to accelerate, either when speeding up to merge on to the interstate/coming out of a turn/or being very slow to accelerate after a stop, like at a red light. About a month ago, it wouldn't start after I filled it up with gas and the check engine light finally came on, so I took it a mechanic. They kept it for a day, got it duplicate the not starting problem, and said it was the "fuel gauge." (looking this up on the internet leaves me questing, because nothing about the definition of a fuel gauge sounds like anything that would cause it to do what it was doing, but they told me that's what the computer alerted as the code for what was wrong.)
It was working fine now when I fill it up with gas, but occasionally still jerks upon accelerating. I haven't looked at the gear gauge to see if it's not changing gears, as I thought at first it might be something misfiring, but I had the spark plugs changed probably a year ago or less. Just based on a quick internet search, I think it might have something to do with the fuel pump. I'd describe the jerking as just that, the car physically jerks until either the gear changes, or it gets power or something, and then once it does it it doesn't accelerate quickly after being at a complete stop, and the engine seems to get louder and while it does move, it seems like when I push the gas petal it has a hard time getting going.
Ford F-150 (2004-2008) :: Bucks / Jerks In OD Around 40 MPH When Accelerating
Truck is 08' with 5.4, 3.55 gears, auto trans. 84k miles. Recently purchased from the TSA fleet trucks, so I have no clue what PM procedures were done prior to me getting it.
I noticed the following: when I get the truck into OD and then slowly decelerate (meaning I let it coast and im not braking) to about 40mph then get on the gas (normal acceleration) the truck bucks hard almost like when your spinning wheels on snow or ice and put the truck in 4wd and the front rear locks. or a limited slip rear that catches when one wheel is spinning.
if I accelerate hard the truck pushes thru it and doesn't buck as bad. I have searched this out and there are several threads about it that describe just about exactly what im talking about, the following have been brought up as possible problems:
1) bad spark plug/s and or coil/s
this seems to be the most common answer to the possible problem.
2)broke valve spring
3) bad torque convertor
So at 84k miles im thinking replacing the spark plugs would be fine to do as a PM. So coils.............should I just go ahead and replace them as well? I found them (motorcraft). does that seem right?
As far as spark plugs, I have already read the horror stories on the 04-08's breaking the plug in the head. I have also read that before 10/07 was the trucks that had the issue. my build date is 02/08. am I good to go with normal removal of the plugs? the best method I have read for removing them is spray carb cleaner down the hole and let it soak overnight and then the next day drive the truck get it nice and hot and remove them right after you park it,,,,
Ford F-150 - 1997-2003 :: 2001 - Jerks While Accelerating Above 40 Mph?
I have a 2001 F150XLT 4x4, V8 Triton engine with offroad package that just rolled over 119,000 miles that just started giving me problems 2 weeks ago. When I accelerate at speeds above 40 mph the truck surges or jerks ( the best way i can describe it ) sporadically unitil I get to cruising speed. If I'm cruising at say 70 mph and go to pass some one and accelerate it does it again. The transmission feels like it shifts smoothly thru all the gears and there is no whining sounds, transmission sounds normal. There is no check engine light, so I assume a diagnostic check might not show anything. Advice from guys at work say possible ignition module, coil pack, transfer case ??? It never feels like the truck wants to stall and it never feels sluggish when accelerating like there is a fuel problem.
View 14 RepliesHyundai - Elantra :: 2004 - Jerks When Driving Uphill / Accelerating
I have a 2004 Hyundai Elantra with 130000+ mi on it. The current engine has 96000+ mi; the original was replaced because the previous owner allowed it to overheat, blew a gasket, and apparently warped the engine itself.
I have owned this car for about 6 weeks now. The car was driven roughly 160 mi from where it was purchased to my residence; no trouble on that trip. However, within the first few weeks of owning it, the car started making a squealing noise when I turned the steering wheel. I took the car to a mechanic and had the belts adjusted. This eliminated the squealing, but I was also told that the CV boot needed to be replaced (they asked if I had been hearing a clicking noise when turning, which I had but had thought nothing of), so I also had that repair done. Problem solved. Car seemed to be running fine.
Okay, on to the current problem. Something else I had started to notice, before I had the belts adjusted, was that it seemed to hesitate a little when going up hills, and sometimes when accelerating. It was a small thing, and I attributed it to my driving style (which probably isn't the best) and the fact that my area is very hilly and the car might be having a harder time with that. Well, this problem has gotten worse; I can definitely feel the car jerking, especially when accelerating (very noticeable when going uphill). The problem also seems to be worse at lower speeds, but I'm not entirely sure that I've nailed that down.
One thing I noticed is that it seemed to become much more noticeable after the last time I gassed up the car. It seems like it's getting worse as the fuel is used up, but that's probably just a consequence of using up fuel as I drive and I'm just looking for connections where there aren't any.
Lexus ES 2007-12 :: ES350 Jerks Sometimes While Driving When Accelerating Or Slowing Down From Speed
I drive 07'es350 and I have felt jerks while driving usually when accelerating or slowing down from speed. Did check with dealer before for transmission after analysis by technician he said it is perfect, recently read on internet and saw fuel filter can be an issue but when called the dealer he said filter is in gas tank and it is lifelong. Not sure what kind of diagnosis I should do to find the issue.
View 13 RepliesBuick - Century :: 2003 - Hesitation Then Jerks A Bit After Coming To A Stop / Accelerating
I have 2003 Buick Century. I started having problems with the car after coming to a stop, accelerating - the car starts to go hesitates, then jerks a bit to go. This does not happen every time after a stop but when it does the service engine soon light comes on. Initially I got the P0401 code (I think) and took it in to a mechanic. They could not find anything wrong with the car but did clean out the EGR valve, that didn't work, they worked on my transmission and replaced other parts, still no success.
I took the car to another mechanic who replaced the EGR valve and several other small parts. I still had the problem but this time the error code was P0420. I took it back again and replaced the spark plugs, O/2 sensor, catalytic converter. That hasn't fixed the problem. The mechanic said that they have taken my car for several test drives and the car has not demonstrated the problem. The error message still reads P0420 even after all of the parts have been replaced. The 2nd mechanic has washed his hands of my problem.
