I recently changed out my stock clutch for a SB Stg.2 endurance clutch. Under hard acceleration my car has developed a serious vibration. I had all four tires road forced balanced but this did nothing. It almost feels as if I have a bent wheel but had no issues prior to the install.
View 24 RepliesBut I have noticed over the past week of driving, whenever the RPMs are around 1000-2000, it is very hard for me to pick up speed, and I can feel a little bit of a rumble/vibration through the steering wheel. So...
If I feather the gas, the RPM increases slightly and you can hear/feel the engine rumble/vibrate. The speed doesn't really increase...
If I hit the gas more than 1/2 way down, turbo kicks in and the car shoots forward.
Is this normal? I find it very hard to add a little bit of acceleration if I feather it, the engine seems to be resisting it, if I hit it any harder, the turbo kicks in around 2500 RPMs. It almost feels as if it is in too high of a gear and the engine has a hard time accelerating a little bit...This is around ~40-60KM/hr
Recent axle replacement and now I've noticed that there is some annoying vibration under hard acceleration and at speeds around 65+.
I just read that cheap replacement axles suck. However, I also read that the OEM are hollow and the cheapos are solid. Could only replacing one side cause there to be some sort of imbalance and cause the vibration?
I bought a B5.5 wagon with 145kmi on it last week. It's a 1.8t with a tiptronic transmission.
Last night, when I stepped on the accelerator for the first time when it downshifted I got a nasty vibration until I let off. When just cruising or accelerating at a normal speed there is no vibration at all. It doesn't matter if you're doing 20 mph or 60mph, it's the same vibration when you accelerate hard.
I'm thinking maybe a motor mount or something?
I have a 99 VW Passat with 2.8 V6, FWD, Automatic tranny and it currently has 94.5K miles. Under semi hard or hard acceleration from either a rolling or standing start, the car vibrates something terrible. Steering wheel has bad vibration and the whole car shakes. If you back off and accelerate very slowly its pretty smoother.
I have had the tires balanced 3 time but the last 2 times the dealer and Sears didn't even move the weights. When cruising at amy steady speed on the highway there is no vibration whatsoever. So I don't think tire balance is the problem. The dealer then put in two brand new half shafts but its no better. I asked them to check the motor mounts but they said they are fine.
Vehicle is a 2002 Mitsubishi Lancer with 123,000 miles. During moderate to hard acceleration in a straight line, especially in gears 1 to 3, the front of the car vibrates. The harder I accelerate, the worse the vibration gets. Once I get into 4th gear and get up to 40 MPH, I can put the pedal to the floor and while it will do it, it is very slight. Check engine light is off.
Interestingly, on the way to work there is a 25 MPH cloverleaf and coming out of the cloverleaf onto the highway, it did not do it until the wheels were pointed straight ahead.
Deceleration, even when aggressively downshifting, is vibration-free.
I do not believe it is ignition related - the car idles fine, has plenty of power under hard acceleration, and doesn't do it when going around that cloverleaf. (As a side note, about a year ago a plug wire went bad, leaving one cylinder with no spark. In this case the engine vibrated violently, but was obviously down on power.)
There are no strange noises in the front end. No clicking around corners typical with a failing constant velocity joint, and no mechanical thuds or sqweaks over bumps I'd expect from a failing ball joint or bushing.
I am having some unusual tire wear on the outside edges of the tires, like you would see with under-inflation, but tire pressure is fine. In my mind, this points to bad ball joints.
It still has the original constant velocity joints and axles as well as the original ball joints. The one motor mount I can see looks okay. I'm thinking in order of liklihood (most likely to least likely):
1) bad axle
2) bad ball joints
3) bad motor mount
Anything else I need to check? Wheel bearings? If I do replace the axles, I will replace the front wheel bearings while I'm in there.
01' Screw 5.4 4wd. Went camping this past weekend and it was the first outing for this truck our TT weighs 6k. When accelerating from a dead stop going straight I'm getting a rumble strip like vibration that last a second. If I take off very easy it doesn't do it. I've seen similar post but no definitive solutions. This truck has less then a 100k on it and so far I've changed the trans filter/fluid rear end oil with modifier and new spark plugs.
Once I'm rolling and hammer down it won't do it. It's more of a annoyance then anything.
I have what feels like a rotational vibration (front to back) during mid to hard acceleration in 5th gear (60-65+mph) and its driving me crazy trying to figure this out. I can slightly feel it under hard acceleration in 3rd gear as well.
I have tried two different sets of wheels (both after market and stock) with no luck. I am starting to think it is in the motor and not the suspension... Or could it be the trans? What can I check/inspect to get how to tackle this?
Info on the car: 2003 Wagon 1.8T 5sp. 40k miles
I just brought my6 Speed Automatic Transmission Phaeton V8 in, because under hard acceleration mostly between 3+4 or 5+6 for a short moment a howling noise with vibration into gear selector appears. I was able to demonstrated it to the Technician, but he said there is not much to do because no Fault code will show up and if he ask VW they will say he needs a reference vehicle to replicate it.
View 24 RepliesI own a Celica '00 and have been driving it for 8 years. In the last year I've noticed that my CEL started coming on. Did some scans and got P0171 error code from Autozone. The Celica was running lean and took some time to accelerate but run fine for a while. It got worse soon and I took it to a mechanic. He diagnosed a bad Cat Converter and he replaced it with an universal one. He also replaced the first Oxygen sensor, Spark Plugs, Fuel Pump and the Mass Air Flow sensor. Car's CEL came back one after 10 miles of driving. At that time I put in a 4" silencer for my muffler. The silencer had a 2.5" opening and worked well to lower the muffler noise.
The CEL was still on and I disconnected the negative on the battery to see if I can reset it. Well, once I connected it back and tried to turn on my Car all hell broke loose. The engine now has extreme sputters, shakes and hesitates to accelerate above 5-10mph. I barely drove it back to the mechanic. He still is not sure what the problem is, he thinks replacing the other sensors and troubleshooting the coils should be the next step. I'm wondering if my silencer could have caused any damage? Also, I'm wondering if there is valve damage inside the cylinder? The code we're getting now is Cylinder 4 misfire. What about the Fuel filter? I don't think it has been changed at all. The car is at 122,000 miles right now.
I am noticing a extreme lag in acceleration. When taking off from a stop it lags really bad then acts like I floored it. My FMP is 48 sometimes dropping to 47.5. FLP is 13 sometimes dropping to 11.5 during starting. Occasionally it doesn't want to start, like its not getting fuel. New batteries 3 months ago. Also has blue spring. Its a 2005 thats never had anything done to the FICM, so its kind of old to begin with. I read in another thread that the FICM relay should be replaced occasionally, so may that could be contributing to some of my probs.
View 14 RepliesI replaced my tires yesterday with Bridgestone Turanza ER33 (245/45/19).
After replacing the tires, there is is an extreme vibration in the front end of the car when braking at highway speeds (60+ mph). Braking at sub 50mph speeds is completely normal. No lights, no vibration while driving. What could be the reason?
Also while removing the lug nut locks, the locks key broke apart (the black piece came out of the key). After like 45mins of trying, finally we got the locks out. I threw them away.
I searched online for regular lug nuts, but couldn't find any beside ebay. The local dealer says I need to wait for 3 weeks to get them from Japan! Where can I get a set of 4 regular lug nuts online?
I'm now running on 4 lug nuts on each wheel. Could this cause a problem? Could the vibration be caused by not having a 5th lug nut in place?
My dad gave me this car a year ago. In great shape however, we've had some issues with extreme vibrating. Motor mounts have been replaced, brakes and rotors are new, ball joints new, and tires still have good tread left. Vibration is so bad that the steering wheel shakes and so do the seats. It happens it park, neutral, and at stops. Its loud and very embarrassing.
View 1 RepliesI have a steering problem in my 2003 forester when i make an extreme right it scrapes and is hard to turn. I took it to morn and they said it was the timing belt, they changed the timing belts and the problem is exactly the same.
View 2 RepliesCould the constant wobble be caused from a bad wheel bearing? The wobbling and vibration gets really bad and it try's to setup an insistent shaking & vibrating at 35mph and I have to slow down to around 18 - 20mph to make it calm down. It sounds and feels like it wants to turn into the 'death wobble thing'. It is coming from the drivers side and after removing the drivers side front wheel, I've noticed the wheel bearing grease has all squished out all around the bearing on the inside of the bearing where the axle enters the bearing right after the ribbed boot. See the attached video. Does this grease coming out all over indicate that the wheel bearing is completely blown out thereby causing this extreme wobble and vibration?
Or could it be a from a combination of a worn tire on that side (which it has) and worn tie rods, ball joints, etc? ...after all the car is 19 years old.
I also have a problem with the heater blower - it does not work at any speed, doesn't even turn on. I can feel heat coming up into the car defrost and vents, but without the assistance of the blower. I can hear the relay click when I turn the heat on and off, and I already put in a new blower motor resistor. Could it be the fan switch itself? Or could the blower motor be blown? The fuses have been checked and are all good.
I have 2015 GTI PP which had the APR Stage 2 with downpipe done about two weeks ago. I pretty much babied it the first week and couldn't believe how quick the car felt with a tiny little bit of throttle.
However, when I floor the car, it accelerates slower than if the throttle is slowly pressed to the floor. If I floor it and then back slowly back off the throttle as I near the upper RPMs the car starts to accelerate like it should have in the first place. The car is a total rocket if I slowly press the pedal towards the floor but if I press the pedal to much towards the floor the car slows down its acceleration that is until I start to slowly lift the pedal.
I'm at 5000ft elevation and its been pretty hot in the 80-103 F degrees. The gas out here is only 91 octane and the car has the 91 octane tune. I have tried gas from multiple stations and even tried an octane booster with no noticible improvement. I went to go log the car with my VCDS and found out that this new car uses a UDS ECU and none of the APR codes on their site match up.
Looking for a compiled list of UDS codes that actually log something useful? Or have a list that corresponds to the APR list of codes?
I just recently lowered my mk6 with h&r springs(1.2 front and rear) and installed wheels and tires from tire rack. I am noticing a lot of vibration at the wheel, pedals and seats while accelerating or moving at higher speeds. I had an alignment done after the springs were installed and all 4 tires/wheels have been road force balanced. One of the tires rated at 20lbs which apparently is acceptable but Tire rack sent me a new tire anyway, which I just had put on today.
Still the same vibration is there. Next step tire rack wants to do is switch out all 4 of my Michelin for a different tire. The guys at tires plus feel that there is no issue with the tires and I think I agree. Could the lowering springs be the problem?
My GTI knocks everytime i acceletate hard from a full stop. The car is chipped stage 1+ from unitronic, apr intake. Everything else is stock, 80.000 km. the sound comes from the front right wheel. I believe it is a top plate, but I'm not too sure.
View 5 Replies1.8T ... Well, initially, engine light came on with a violent shake from the engine compartment. It was really really bad. I thought the engine mount just broke off or something...
First I looked at the coil packs and the spark plugs. The spark plugs were pretty old (I got the 02 Jetta 1.8T at ~140k miles for 1k, so no surprises). Spark plug on cylinder 2 was real bad, and that was the cylinder with the misfire code. Got a new set of spark plugs first. It worked a lot and the violent shuddering mostly went away.
The engine still idled erratically jumping and dipping at idle, even with the A/C off. So I replaced the coil pack on cylinder 2 after doing the coil pack switch test... After replacing the one coil pack, the engine idles like like it's new.
When I put the car in neutral and rev the engine to the redline, it revs nicely, very smooth. When I drive the car, when I accelerate reasonably slowly with the traffic, the car drives just fine. If I keep the car in lower gears and use light throttle to accelerate, it is smooth even past the rpm range where the turbo would be spooled up.
It is only when I dip into the throttle a bit more (no where near full throttle) to try to pass a car or accelerate just a bit harder, a little past ~2200rpm ish which is when the turbo starts spooling from the sound of it, it starts shuddering badly, and check engine light comes back on. The code shows misfire in cylinder 2.
My guess is there's something off with fuel system. My non-mechanic thought process is that maybe the injector is clogged and when it's light throttle, light acceleration, it injects little fuel and its ok, but when under heavier load / throttle, it tries to inject more fuel, but can't because it's clogged...
I am getting a ticking noise under hard acceleration. Dealer told me the exhaust is touching the heat shield but did nothing about it. It's driving me crazy...
I may have to pull the trigger on this Borla I found for 700 shipped and new. Trying to keep my promise to myself to drive the car stock for a year b4 any major spending. That's out, I can already tell.
I've had this happen a couple of times before on my '10 GTI - I'm on the freeway and I decide to throw the DSG into S mode and punch it, seconds after I bring it back down to D and normal engine speeds I can smell an odor that reminds me of the cat going bad - sort of like sulfur or something burning (not rubber, though). This is with my windows rolled up and A/C re-circulation turned on. What I should be checking?
