Golf/GTI VII :: TSI Accelerating On Its Own At Low Speeds
Nov 29, 2014
When I first start up my manual Golf TSI and shift from 1st to 2nd gear and take my foot completely off the clutch, the car begins accelerating on its own before I give it any gas unless i put my foot back on the clutch (or brake obviously). I'll have no feet on any pedals and it will fairly quickly go up to 15 mph before it stops accelerating. I've also had it do it in 3rd gear. i tried to let it go on it's own to see how much it would accelerate and had to finally put my foot on the brake because i was coming towards a speed bump.
I have a Launch Edition, so there's no cruise control, so obviously it has nothing to do with that, and it's not going downhill. It only happens during the first time I start my car for the day, or after having not driven it for several hours. I've never experienced it with any other manual cars I've driven and I though it seemed odd. My friend has a MK 6 and he said his does the same thing, so I don't know.

The last couple of days I've noticed a strange sound that come on under boost accelerating at highway speeds. It's a harsh ssshhhh sound that rises in frequency with engine RPM, sort of between a wood lathe and a bench grinder. happens under mid to WOT. It almost seems like I am loosing a little HP as well but I can't confirm that. It's loud enough to hear it in the cabin and with the windows down I can definitely hear it. It's not really fluttering, that I'm used to being on my 3rd tuned 2.0T

Car shakes real bad when it turns over and then at different speeds. 25-30 it'll shake more, along with 45-50 and around 70 mph.
Mechanic friend says motor mounts which would make since cause the one thats visible has cracks in the rubber.
But the shop my father takes the car into says it needs a new drive shaft.

I have an 04 celica gt with around 168 k miles on it. Recently I have noticed a distinct metal on metal rattling noise whenever I accelerate at low speeds. It seems to be my exhaust as when I rev it up in park it makes the noise. But it doesn't ever make the noise when I'm on the expressway or cruising at back roads speeds. When I got under and looked at my exhaust everything looked normal?

I have a 2008 Saturn Astra and there is a high pitched squeeling sound when i accelerate from a stop. It has been happening since last year but seems to have gotten worse. It only happens in the summer time. It squeels only when accelerating at low speeds. if I accelerate quickly the sound goes away. but will come back if i come to a stop and accelerate normally again. It doesnt start from 0 RPMs but only at low rpm. It only happens when I first turn on the car and accelerate. If I have been driving for a few minutes and then accelerate from a stop it doesn't make any unusual sound. It happens in reverse as well as drive.

I have a 1998 Jeep Cherokee with a straight 6. Lately I have been having trouble with hesitation when I accelerate. It happens at all speeds. It is a stick shift, and as I push in the clutch pedal, the engine races a bit and then as a let it out the car hesitates and/or bucks if I don't give it a shit load of gas. Also, if I let off the gas completely and then try to accelerate quickly it will pause and buck unless I do it really gradually. This problem is intermittent, so I am thinking it might be something with a sensor. Also, if it stalls out completely, restarting the car requires me to hold the gas to the floor. I have already replaced the camshaft and throttle position sensors. Not sure what the deal is.

I have owned this car from new and it currently has 32k miles. The only fuel used has been 85 octane or occasionally a tank of 93 octane. There is a distinct hesitation when accelerating from speeds of 10 to 15 mph and I do not believe it is due to the transmission shifting. I did move to my current state,California, from Pennsylvania and was told by my local Hyundai dealer service department that because California has a different gasoline formulation from most other states as well as a summer and winter blend to reduce emissions it is recommended to run a bottle of injector cleaner every 15k miles.

I've got a 2002 Toyota Camry with 96,000 miles on it. Car has been running fine for years but on a recent 250-mile drive I noticed a whirring noise (almost like the engine of a remote-control electric car). The noise is faint, but definitely new. I'm fairly sure it's coming from the under the hood, or at least from the front half of the car. No vibrations. The noise is only audible at highway speeds, and really only present when I'm accelerating (or on cruise control). It seems to get slightly worse if the car is climbing a hill.
Some things that have been worrying me:*I left the car in a friend's driveway all summer. Could that have anything to do with it? (There were no noticeable problems when I got back, which was months ago--when I came back after two months, I simply re-connected the battery and the car started on the first try).*I had a transmission fluid change about 2K miles ago. It was at a Jiffy Lube. They "flushed" the old fluid. They claimed they used the correct Toyota brand fluid. (I've since read that flushing the old fluid can be a bad idea for older cars.) Could this have something to do with it?*I just had my snow tires put on two weeks ago (and this is the first long drive I've done with the snow tires on). The guy who changed my tires took about 2.5 hours to do the job, saying "this is only his second week." The car is steering fine, and not drifting or anything, but could that mechanic have done something to the tires that is causing this highway-speed, acceleration-only whirring noise?

My 2007 Hyundai Accent gs shakes really bad while I am accelerating at lower speeds. I thought the front driver's side tire was loose or possibly had an air bubble, but could find no evidence of such. The rim and the tie rod looks fine, but it is shaking bad. It pretty much stops shaking when i reach higher speeds (60+mph), but when I am stopped and need to accelerate or turn it gets frightening.

My 2007 Hyundai Elantra SE (Automatic, 69,400 miles) makes a grinding noise when I start to accelerate from 40 mph. I sometimes hear a noise that sounds like an airplane wheel being activated when I'm driving at lower speeds driving around town. Could this be the transmission? Who should I take the car to?

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.

My '01 Aztek has a very odd shimmy. It only happens when turning right, at highway speeds, and when accelerating. Not when turning left, and not while just 'coasting'. Only when accelerating.
The mechanic replaced a tie rod end, and that seemed to fix things for a few hundred miles. But now it's back and is happening at lower speeds.

My engine doesn't run smoothly (like a misfire) when accelerating at hwy speeds, especially when the outside temp is above 20 degrees... the warmer the temps are, the worse it is.
I have a code P0431 - "warm up cat efficiency below threshold (Bank 2)"
Is it an O2 sensor problem, and if so, which one is it and what is the Hyundai p/n for the sensor? Bank 2 is in the front, correct?

Took car in for normal service (69,000 miles) and had Tranny Fluid Service completed. When I took the car home I noticed some slight tranny slipping while accelerating up to highway speeds (so assuming 4th to 5th gear, maybe 5th to 6th). Took it back to the dealer and after a week it had a new transmission. Took it home and it slipped again, also only accelerating to highway speeds. Took it back and they told me they reset the computer that monitors my driving patterns. OK, not exactly sure what that means. So, now driving to work this morning it slipped (or maybe hesitated is a better word) again when accelerating from about 55 mph to 60 or so. Car has never had issues like this before, gas mileage is still in the 30 mpg range.

2007 Sonata 3.3. Crunching, clunking noise at low speeds, braking or accelerating away from stop lights. Noise disappears at speeds over 25-30 mph. Noise can be replicated by rocking car forward and backward while in park, with engine turned off. Rocking side to side does not reproduce noise. Bouncing car suspension at all four corners does not reproduce noise. Hood open, rocking forward and backwards, noise seems to be coming from behind engine, and with hand on engine motion can be felt. I'm thinking engine mount, but how can I get a good look at it to check?

I test drove the sc 430 the other day, I found it very smooth and very soft ride. I noticed that when I accelerate the car feels heavy as if it lacks the torque. Is this normal?
Also, the steering felt loose at high speeds above 60mph. Is this normal?

Why I am smelling coolant? I have a 2004 6.0 SD.It generally happens when accelerating up to freeway speeds or passing cars, Medium to hard acceleration and the smell is strong and will go away after a few min. The obvious thing is to check for a leak but I haven’t seen any.

I just bought my first R32 a few weeks ago, 100% stock and spotless with 75k miles on it, after about a week, the car started shaking when coasting (immediately after removing foot from the accelerator) around and above 50 mph. When it first started it was pulling to the left and shaking in the wheel, i went and had an alignment done and it seemed to only dull the shaking, the tires were alittle worn so i went and got all new tires and it has taken the shaking and pull completely out of the steering wheel, now only the car itself shakes, not while accelerating, only when i take my foot off the accelerator. I've been told everything from motor mounts to spark plugs

What would be the fastest way for accelerating above 70 mph? d, s or manually and from what gear? Also for those of you that drive on s on the highway at what gear (how many RPMS) is the car driving at 70 mph and is there an actual difference in driving on d, s or manually when in speeds exceeding 70 mph? Would our cars top speed be reached on s or manual mode? I would like to have a few responses, because having a performance car and not being able to drive it properly bothers me a lot, especially when my car was barely faster than an accord v6

I've been trying to figure out what exactly is going on with my car but its hard to explain/describe it so I've decided to video it..
Driving + shifting + holding my phone + my GTI is spun all the way down on coils = shakie video.
In Video #1, I'm in 4th gear at 2800 RPM and gave it full throttle. Watch it closely at 0:04 you will notice how the RMP just jump back a little and then continue accelerating while the boost is holding at 15psi.
Video #2, same story at 0:04 except the boost jumps back as well.
It does NOT seem normal and im not sure whats wrong and where to even start.
Slipping clutch?
Diverter Valve?
Boost/vacuum leak?
Turbo into DP leak?
My GTI is APR Stage II, intake and catless turboback exhaust.

I'm trying to figure out this noise I'm hearing whenever I accelerate. I can't tell if it's the turbo or something else. It doesn't have the smooth turbo spool sound like my mk4 GTI so I'm wondering if something is wrong or this is just how the car is....
It sounds like some kind of air induction but a little clangy at the same time. I'd try to record it but I don't think my iphone would pick it up.
