Golf IV / Jetta IV :: Hesitation / Bogged Down When Accelerating
Apr 19, 2016
I have a VW golf 2.0L AEG with 5 speed manual with 150,000 miles. Lately, it has been hesitating when I accelerate, not all the time but intermittently. It also shakes when I downshift, especially in lower gears. I have replaced the dog bone, the spark plugs, fuel filter, clean the MAF and tried another ignition coil. Nothing really worked. The only that worked a little (like a day) is when I disconnected the MAF sensor. I tried to do it again without much success. I scanned the car with VAG COM and I have no code.
The original clutch and original fuel pump are on the car. I checked the timing belt and it is in good shape. I was thinking that I may need a new clutch but I don't have nay slipping, just the vibrations when I downshift. I thought maybe the motor mounts are bad but I don't see excessive play when I rev up the engine. I sprayed the spark plug wires and ignition coil with water without any issues. What I should do next? Motor mounts or clutch? Bring it to VW for diagnosis?

I bought a cheap golf in february. It's an akl engine (1.6sr). Everything was fine on the way home. The car then wasn't used for like a month or two, and was stored outside. When we started using the car it gradually got more and more stuttering. At first it was just a slight stutter when accelerating, but now it's horrible. It will stutter and hesitate like crazy when accelerating or under load, but will cruise just fine at normal rpms. So far I have changed the air filter, fuel filter, spark plugs and a bad spark plug wire, but nothing has worked. I bought a vag scanner but couldn't find any codes. The idle isn't too bad but not perfect. What the problem can be?

I'm having a misfire issue on my 1.8t. When I go into high boost I'm getting bogged down and misfiring.
I plugged in my obd2 adapter and it gave me a misfire on cylinder 3. I since cleared the code to try and see if it was a coil pack by switching it to another cylinder, but now the cel won't come back on although the problem persists.
I have recently changed the plugs and the car was fine. I then added a fuel injector treatment and the misfire started shortly afterwards. (coincidence perhaps). It's frustrating as I can't rule out coil packs as my cel won't come back on and my code reader is not displaying any faults.
I did previously have a cel with something about fuel trim bank 3? I am also sure I have a boost leak as the car whistles pretty loud under boost.
Also worth mentioning I have a bit of white smoke sometimes but I'm not using oil or coolant and they are not mixing either. I'm at the end of my tether with this car and just want to try get it back to normal.

Happened last night two blocks away from home. The idle seemed a little rough at start-up but didn't think much of it because the coolant temp was only 132 degrees. Pulled out of the driveway up to the stop at the corner. Totally bogged upon accelerating, went a block, then came the sound of a hubcap rolling down the street along with a check battery light, no power steering, and REALLY sucky brakes.

Have a 2004 Jetta, 2.0L BEV auto..has 124,800 miles on it...when cruising on the highway the car seems to momentarily lose power like as if i let off the gas. Car has the original everything for the most part. Did the water pump and timing belt 2k miles ago. Maybe alternator? fuel delivery?

Car is a 20th, 1.8t 6-speed.
I noticed something the other day that is happening occasionally on acceleration. At partial throttle, usually pulling away from a light or stop sign, I get this weird hesitation. It only happens at partial throttle and usually only in first, sometimes in second. As the RPMs increase up to around 3k, it's as if I lose power for a second. You can feel the car stop accelerating for a second, then it begins to pull again.
If it's under heavy acceleration it never happens. It doesn't feel like the clutch slipping, more like the motor hesitating, but there's no noises or missing or anything like that. The RPMs don't jump up or anything. It's like for a second it's making no power, then it comes back.

I decided to take out the throttle body and clean it with throttle body cleaner that I got from autozone, after I put everything back, I started my car and the motor was shaking and smoking a lot out the muffler and just would not be drivable at all. the RPM was just going up and down and hesitating bad. later I took off the spark plugs and they were very much burnt black at the tips and that is probably not normal right? but I replaced them with NGK BKR7E spark plugs and it still gave me the problem.

I am going to be looking into this a little bit tomorrow with an oil change and noisy hub bearing.
Car : 2002 Jetta GLS 1.8t stock 5spd ~165k miles
Symptoms : Light acceleration (day to day), After shifting into 2nd gear, the rpms come down to 2-2500 range, while accelerating it feels like a hesitation for a couple seconds then continues to go without issue.
Moderate acceleration (casual hwy on ramp, stoplight fun), After shifting into 2nd gear, the rpms come down to the 25-2800 range, while accelerating it feels like a hesitation for a couple seconds then continues to go without issue.
Hard acceleration (short hwy on ramp), After shifting into 2nd gear, the rpms come down to the 28-3100 range. I do not feel any symptoms noted above.
The hesitation felt is enough to cause the car to feel like it had a short loss of power. This does give a jerky feel.
My thoughts : I know there were issues with the coils in this model/year. I have verified through the deal that the vin had received the replacements but unsure if they are the actual replacements. My dad thinks it may be turbo related (which is also stock and never pulled apart to my knowledge).
I found that this KO3s turbo should be fully spooled about 2200rpms. It seems to coincide with my lower rpm accel that maybe I am loosing some of the spool and feeling that?
Other Info : Am I way off or is there anything I can check for easily? I am not very knowledgeable in turbos beyond their basic functions. This is also my first turbo car. I have owned the car 2yrs now. It seemed to have always been there but I don't recall noticing it on the initial test drive. The trans has been replaced since noticing this for other reasons but did not correct this.

2003, Jetta 1.8t, 5 speed, 76,500 miles ... The other day I was driving and all of a sudden I had a hesitation in 3rd gear. I have relized since that this hesitation occurs in 3rd 4th and 5th gear, but not 1st or 2nd. I am going to change the spark plugs tomorrow in hope to fix this problem. The hesitation occurs whenever you get into the gas and begin to accelerate(typically around 3000RPM and up). There are no dash lights on at all and the cars is running fine besides the hesitation.

The Electronic Power Control light in my 1999.5 Jetta GLS VR6 came on a day or two ago. Now it hesitates like crazy even after I've already pulled out and am trying to accelerate. Is there any common problem/malfunction that would cause the light to come on, and is there any correlation between the light and this symptom? Also, the check engine light came on.

I switched my front rotors 4 times in the last 4 years.
I know you probably thinking its the driver. I've owned the car since 2012 and have only put on 46000 kms.
The rotors vibrate and have that weird stop and go hesitation when braking.
Is it simply OEM or nothing?

I had a motor go bad, overheated, replaced it with another motor. Got it all back together and upon test drive I am having a low rpm (below 3k) bad hesitation/misfire. The engine runs just fine at wide open throttle.
First thing i checked for were plug wires and vacuum leaks. The only difference between the old block and the new block is the fact that i replaced the MAF with a new one, as i was getting a maf code on the old engine. I can't get it to throw a code...

I have been experiencing this one for quite a while now. The car is a 2003 GTI VR6 24v. It is stock other than a 3" hole in the bottom of the airbox to pull in cooler air.
When I am sitting in traffic, and in 1st or 2nd gear, keeping a consistent speed (10-15mph) and application of the throttle (not moving my foot at all), the car sometimes just decelerates/hesitates/bucks a little by itself, and kind of feels like it is hiccuping or not getting enough air or something.
At high rpm, or in any gear above 2nd, I don't feel the hesitation and the engine runs great and pulls hard. No MIL lights on the dash, and no other problems with it.
Is this normal for manual VW's? Or maybe the hesitation coming from the engine not getting a consistent airflow from the hole in the airbox?

Coming home, doing 50 or so in traffic. R has been feeling bogged down when shifting from 1st to 2nd and it would start around 2K. Felt like someone would tug on the R, holding it back. Driving along, don't hear a pop or loud sound, just a poof of blk smoke then a TON of white smoke.
I limp my way to a parking lot and let it sit. I call the wife as I'm 6 miles from home. I'm thinking blown head gasket or something else. I call Benji at NGP Racing and explain to him what happened. He said if it was the HG that there would be a milky look to the coolant. Checked and nope.
I start the R and let it idle and it seems fine. The wife gets there and follows me back home. Still feels bogged down as described above. At one point a huge plume of thick blk smoke comes out of the rear. she said enough that she couldnt see the R.
Last night I checked the oil, seemed low in the dim light. I know my fault. I put in 3 quarts. Looked at the exhaust tips and they are blk. I mean you can see oil down into the pipes. Noticed some oil had been leaking from the aftermarket oil cap that doesnt seal as good as the OEM I take it.
Info:
118K miles
Had been hearing some noises from the timing chains.

I just purchased a 2001 Jetta Wolfsburg with the 1.8T, 5 speed, and 169,000 miles. I need to figure out the engine hiccups. The check engine light is on. The car seems to hesitate between 2000-3000 rpm when the motor is lugged (pulling a hill, passing, etc).
I had the codes pulled at Autozone and came up with the following.
P0172 (Bank 1 System Too Rich)
P0300 (Random Multiple Misfire)
P0302 (Cylinder 2 Misfire)
P0420 (Catalyst System Below)
P0455 (Evaporator Emission)
P0411 (Secondary Air Injector Incorrect)

So this morning when I started my car to warm up everything was fine. I went inside to make some coffee and I heard my idle change slightly and didn't think to much about it but when I got in I could feel my car shaking a little bit then when I pulled off my road there was a little hesitation in first gear taking off and when I would shift I would get a little rev hang between gears. So I've realized when idling its slightly fluctuating between 6-7 hundred rpm. I have no loss of power and it has not hesitated since the first take off. I'm thinking its something to deal with air. I checked my airbox and realized the bolt closest to the battery wasn't threaded so I fixed that and tried looking for any leaks but haven't found anything.

Recently I switched from Revo software with 440cc injectors to Unitronic with Siemens 630cc injectors. After swapping, the car has developed a hesitation issue. It only happens when driving a consistent speed in one gear, for example going 45 in 5th, the car will feel jumpy and hesitate to accelerate with a seeming loss of power. Replaced spark plugs with new ones and the problem still persists. Problem never happened with old software and injectors.

When i got my 2000 jetta vr6 it has a CEL for misfires. Searched this board and google already. Im thinking injectors (havent checked yet) I noticed something weird the other day. At a light i get the CEL flashing. Then after a bit it will come on and stay on. I plugged in my generic reader and deleted the codes. When the CEL is on I get loss of power and hesitation. When its deleted the car runs better. I get my power back. I looked in the coolant tank and see no bubbles. Could this be the ECM? Im still going to get injectors but want to buy the gasket and anything else I am going to need to put it back together. I already cleaned the MAF, replaced some vac lines, coil pack, wires and checked plugs (gapped at .28) ...

When my car is at idle or cruising the AC works well. When I'm driving normally from stop light to stop light the AC gets warm.
I did have the pressures checked and they topped off the refrigerant. They also said the compressor is working well. I had all this checked before it started getting warm during accelerating.
Are there some things that I can look at?
