Golf/GTI VI :: 2001 - Under Hard Acceleration Growl / Rumble


Feb 1, 2010

I took delivery of my GTI last Friday and I'm loving the car so far. Coming from a 2001 Miata LS, this car is so much smoother and quiet. I especially love the engine and the sound it makes, or lack thereof. It's barely noticeable until I stomp on the gas and then there's a lovely ... growl? rumble? I'm trying to think of how to describe the sound to friends who cannot hear it firsthand.

BTW, I haven't noticed the dreaded turbo wastegate rattle between 2-3K RPMs so, no, it's not that.

Golf IV / Jetta IV :: 2001 - Rumble And Idle Noise

I have a 01 1.8T and I'm looking for a little more rumble and idle noise currently my set up is a 3 inch downpipe cat less and a resanator delete into a stock muffler with modified tips, I had the downturn cut out and ran it straight out the back. Anyways my question is what muffler would you recommend that gives a nice idle and aggressive acceleration with my current set up ( the 3 inch downpipe and res delete).

Santa FE SM (2001-06) :: 2004 2.4L - Vibrating Noise On Hard Acceleration

New here - 2004 Hyundai Santa Fe 2.4L Autostick//great car so far, but this is annoying me!

I can't feel any vibration, I just bought the vehicle and wondering where this noise might be coming from? If you rev the engine over 3k there is a strange vibrating/humming/rattling?? noise but you can't feel any vibration. I was thinking it might be the plastic cover on the engine or maybe something loose? I've already had the belt tensioners/belts checked out and that is not the issue.

It also sounds like a ricer when accelerating heavily (but from inside the cabin) there aren't any exhaust leaks at least I don't think so...

Golf/GTI VII :: APR Stage 2 - Hard Acceleration

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?

Golf/GTI VI :: MK6 Knocking On Hard Acceleration / Right Turns

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.

Golf IV / Jetta IV :: Shuddering Only On Hard(er) Acceleration

1.8T ... 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...

Golf V R32 :: Ticking Noise Under Hard Acceleration

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.

Golf/GTI VI :: Extreme Vibration Under Hard Acceleration

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.

Golf/GTI VI :: Odd Smell In Cabin After Hard Acceleration

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?

Ford Ranger / B-Series :: 2001 Edge Really Rough At Start Up / Stalls On Hard Acceleration

2001 Ranger Edge 3.0. Like the title says, when I start my ranger it idles really rough. If I give it gas it shudders like it's gonna die. After about 2-3 minutes it smooths out. If I'm on the interstate and down shift to pass someone, while accelerating it feels like I have a misfire (no CEL given) not all the time though. I've changed plugs and wires and it stopped doing it so I thought I had it but, it continued a few days later. Then I changed the fuel filter and it stopped again for a few days. Well it's back again. I'm thinking it's the fuel pump but I wanted to check here before I take my truck bed off. I also checked for vac leaks and I'm all good there.

Golf IV / Jetta IV :: Under Hard Acceleration In 3rd - 5th Car Will Jump And Jerk

I just recently bought a 2001 Jetta with the 1.8t (AWD) because it had low mileage and a reasonable price. I've never owned a VW before so I know very little about them in general. This is my second vehicle with a turbo, my first was a Saab 93.

When I purchased the car it had the check engine light on and the codes were Vehicle Speed Sensor and Secondary Air Injection Pump. I was able to get it to stop throwing those codes just by cleaning off the components and reconnecting them. The only predominant problem I've been experiencing is that under hard acceleration in 3rd-5th the car will jump and jerk. Its almost like the car isn't getting enough fuel/air but I'm not entirely sure if that's an accurate diagnosis. I've ruled out transmission issues because there are no problems when driving at a slow-normal acceleration. Any insight on where I should begin to fix this issue would be welcomed because I feel as if my motor mounts will break due the force of the jerking.

My last issue has to do with what happened yesterday. My check engine light came back on randomly when I cranked my car. I had no issues the previous day (besides the aforementioned "jerking) so it seemed odd but what really worried me was when I started driving. Whenever I would release the accelerator the car would slow down suddenly as if I applied the brake. The problem continued throughout the day until I got the codes checked and they read Vehicle Speed Sensor (which I've seen has numerous issues from the factory installation) and the Bank 1 O2 sensor. Today I started my car and the check engine light wasn't on.

My car drove like normal (still the hard acceleration jerking but no dramatic deceleration when I release the accelerator). Now to my question, can an O2 sensor cause a problem like this? Maybe the MAF is bad? Not even sure if this vehicle will throw a code for the MAF ...

Golf/GTI VI :: In 3rd Gear Under Hard Acceleration - Fuel Cuts Out

Lately I've been having trouble with my car in third gear under hard acceleration while in tip mode with DSG. I have been Stage 2 since April and it hasn't really been an issue until recently.

The best way I can describe it is when you get into 3rd with your foot on the gas the car stops accelerating and kind of gets stuck. I have to completely let off the gas and before it "wakes up" again. I feel like it's been getting worse in worse, but it only ever happens when I try to push it hard.

No problems in auto mode or sport, it's just a major let down. Could the fuel pump be the culprit? It just feels like the car doesn't want to move for a second or 2, like no response from the gas pedal.

Ford F-150 (2004-2008) :: Rumble / Shudder In Truck On Initial Acceleration

Just rejoined this Ford gang after years absence. Used to own "The Muny Pit", a '79 F-150 4WD monster with a '69 429... constantly breaking something. Anyway, where to look on my '08 F-150 XLT 4WD with a 5.4, 83,000 miles. Searched the search bar for my title and found a post on an '00 Expedition describing similar issue than mine... for about 6 months now when I accelerate either from stop or a crawl; forward or reverse; more so when turning, but does do it wheels straight.

Upon initial acceleration I have this horrendous rumble / shudder in the truck, like the grinding metal bearing sound/feeling felt when the pinion bearing went out on my '79 (only felt it seconds before the 9" rear pumpkin exploded). Once rolling it stops. I have checked all wheel bearings.. I have check all the suspension joints... everything looks fine, no obvious issues. The only suspension mod I've done is a 1.5" leveling kit when brand new. On the Expedition two replys suggested changing the transmission/transfer case fluids claiming it cured their vehicles.

Ford F-150 (2009-2014) :: EcoBoost Engine - Slight Rumble On Acceleration

I picked up a 2014 F150 with the EcoBoost engine a couple weeks back and while so far I love it, I can't get over how quiet it is. So, to my question, has anyone done anything with the exhaust to get some of that truck sound back. A slight rumble on acceleration would be nice to have and maybe get some gains out of it, but thats minimal.

Golf IV R32 :: Stuttering Under Hard Acceleration And Battery Voltage Dropped

Recently the car was stuttering under hard acceleration and battery voltage dropped, I have a batt gauge. Got harness replaced and symptoms are gone but this must be happening to others with or without symptoms.

Check your fuse box on top of the battery. The alternator harness wire turns silver after many years of use. Your battery volts will drop also and you can see it with a gauge. I changed this harness and symptoms went away. It's the thick gauge wire all the way to the left. This needs to be changed with a new alternator. Many people prob don't know their harness is causing high resistance affecting the quality of smoothness.

The hotter the car gets the worse it gets if you have this issue. More RPMS, is more electricity and more resistance. There is no CEL for this. The harness should be copper colored, if it turns silver it's old and needs to be swapped. If you drive low Rpms all the time you won't notice. But it's an R, who does this?

The harness is around $90 and car has to be in service mode to get to the alternator. This is my 2nd alternator and kept my original harness when replaced, bad idea.

It takes under 20 seconds to pop the hood and open the fuse box to see what color your harness cable is. I expect most to be silver not copper, but whether you have symptoms or not depends on severity.

Golf IV R32 :: CEL Blinking - Slight Hesitation Around 2500 Under Hard Acceleration

The problem started with a slight hesitation around 2500 under hard acceleration. Then it became more pronounced from 2 to 3.5k. The CEL would blink when it happened for more than a few seconds. Eventually the CEL stayed on. Now the car idles roughly with a periodic thump feeling, and any time a load is put on the engine, it feels very rough. I don't have VAG-COM, so I don't have any codes.

Golf IV / Jetta IV :: Occasional Misfire In Hard Rains / No Acceleration

2002 AVH Jetta Wagon. When I got the car back in 2012 it had 121K and I changed the wires (ngk blue 57021) and plugs (ngk platinum) and she drove like a dream. A couple of months later I started having issues with wet weather and moisture causing misfires so I did the JB WELD fix and though I'd still get the occasional misfire in hard rains it lasted me pretty much until very recently, when I decided I needed to put in a new coil because the problem was getting worse (hardly starting up after a rain and bucking wildly till things dried out). Yesterday, I replaced the BERU with a new HUCO and the car started up fine and drove fine all day. I think there was a lot of moisture in the air last night and possibly some rain but this morning, SAME PROBLEM with a new coil. Misfiring like crazy, no acceleration.

I thought the NGK wires and plugs I got were rated to last beyond 20,000 miles. At this point should I assume the wires are to blame? Split somewhere or something? It's definitely related to water and the electrical system.

Golf IV R32 :: Hard Acceleration In 3rd Gear / Momentary Loss In Power

Having problems where sometimes the car won't go into gear, other times it's fine? The problem started after some hard acceleration in 3rd, there was what felt like a momentary loss in power. I dipped the clutch as I thought a boost pipe had popped off, all was fine (still seeing boost when revved). After this it got progressively harder to get gears, finally resulting in not being able to get into gear at all.

I found I could get it into 1st with the engine off and could go up gears normally, but couldn't change down without stopping and turning the engine off. The clutch is working fine, the biting point is normal. The problem seams to come and go randomly, it will work fine for a while and then start playing up again. When working the gearbox feels normal, there is no grinding or wining noises. I can move between gears normally and do clutch less gear changes.

There is now a vibration which can be felt at 1000rpm when stationary. It feels like it coming from the engine/gearbox and seems like something is out of balance as it shakes the whole car. The car is on 91k, supercharged running 470hp & 370lb/ft (at flywheel) and is fitted with a Spec stage 3+ clutch and solid flywheel.

Golf IV / Jetta IV :: 2003 - Hard Left Pull Under Acceleration

I have a 2003 Volkswagen Golf 2.0L 5 speed manual. Over the last 10,000 miles a problem started where on the highway in 5th gear, if i try to speed up by putting the pedal down, the steering wheel moves itself to the left and the car steers to the left. The wheel returns to the original position when i let off of the gas. its scary at high speeds and has become so bad that I can feel it accelerating at low speeds too.

The alignment is off and the steering wheel slightly to the right. when I put the gas down and it goes perfectly straight and when i release it goes back to the right. it has 126,000 miles on it. I know it needs tires, shocks and an alignment job but don't think that those factors are causing my problem. Could it be the motor mounts?
