Golf IV / Jetta IV :: Hesitation / Misfire At Steady Cruise
Feb 18, 2016
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...

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) ...

I have a 2011 GTI which has about 46k miles on it. The car is stock other than some VagCom stuff. Over the last few months I have noticed a worsening problem which is getting bad enough to start being annoying. Under very light throttle such as cruising along or rolling off the throttle to shift, the car has a slight miss, almost like it's surging. It happens in any gear, typically around 1500 - 2200 rpm, and I first noticed it actually on the highway using cruise. It seems to happen most before the car gets nice and warm. It has not thrown a CEL, but I have scanned it and found some misfire codes, although I believe those to be from a really rough cold start which sporadically happens maybe once every six months (last time a couple weeks ago).
I have it booked into the dealer but I can't get there for a couple weeks. I don't think it's coil or injector related because it runs fine under high load and high rpm. Fuel filter has maybe 2500 miles on it, always use Shell 91. I really think it's probably carbon buildup but I am hoping the dealer doesn't just give it the old "cannot replicate" since the car is not triggering a CIL yet. It's pretty obvious when you drive it though that something is off. If they play that game I'll probably just go ahead and do it myself.

It is difficult to explain (and google) but my 1.4 16V Golf 4 does this sometimes: while driving at a steady speed car jerks for a moment and revs drop quite much, a moment later it is fine. It feels like I had stepped on the brakes, but when I actually try that the revs won't drop as much. Like my engine seizes up for a fraction of a second but there is no noise. It has done that actually for 3 years, but it was really rare, about twice a year, but now I have had those jerks three days in a row.

I have a really weird issue with my 2003 Ford Focus. Manual transmission, just over 50,000 miles. I've been noticing a stumble or hesitation (like the engine is cutting out) at steady speed, but ONLY when it is snowy out, more if it's windy as well. I don't recall that this happens if it's rainy or foggy. All maintenance is performed as specified, to include air filter changes.

I have a 2000 Tahoe with the 5.3L V-8, 351,000 (yes that is correct) miles. Runs great except it has recently developed a stutter, hesitation, skip, I don't really know how to describe it, under acceleration or at steady speed. This is an intermittent problem and it is driving me batty. The only codes are a P0420, maybe after 350k miles it needs replaced? Would that possibly cause this issue, or am I looking at something more sinister?

Model 2007 Toyota Camry 4cyl
Milage 121K
Service preformed by me @ 119K:
- changed sparkplugs (toyota part)
- changed drivebelt (toyota part)
- changed new battery (Costco battery)
- changed engine air filter(toyota part)
- Oil change every 5K
- Trans flush (toyota part: Type WS fluid: 16 Qts)
- Transflush also preformed at 60K
Problem: So beginning of this week I was driving on the HWY and as most of us like to overtake while driving, so I stepped on the gas pedal hard. The vehicle downshifted to lower gear and RPM got up to 5 to 6K for 3 seconds then suddenly vehicle slowed down. When this happened it was like hitting a brick wall. I don't know if the engine braked so hard or transmission did. I never had this happen to me.
No transmission noise or engine noise. Car at the moment runs fine. The problem is that now every time I step on the gas from steady cruise, RPM will rise up to 4K or so and I do feel that vehicle down shifts but RPM will drop down to 2K and slow climb as vehicle picks up speed. So during this time I can floor the gas pedal but very very little response of the engine. Its like something is holding the vehicle back.
So I went to autostore to see if I have any pending codes as no check engine light or abs...
One pending code came up: C1241 (Low Battery Positive Voltage)

2005 4cyl. Vue with 54K... Steady CEL. Runs great. Absolutely no problem accelerating. Don?t hear or feel any misfiring. There is a slight rumbling sound when I first start to drive the car, but to me, the sound doesn't seem come from the engine, but rather underneath the car. It goes away when I continue to drive. Since winter began, I occasionally feel a very slight hesitation during idle?happened once or twice lately.
Again, I only feel justified in mentioning it simply because of the codes that were generated. None of my passengers have made a comment about the idle or the drive. My friend, however, made a remark that occasionally, there is a very very very slight hesitation at the downshift when braking. No crack in gas cap. Great fuel economy. No problems accelerating at all. Never hear or an actual misfire, which I take it, means a problem when accelerating, a jerking, or popping noise.
Took it to a dealer. Codes were 0300, 301, 302, 303, 304?302 generating most often. Dealer recommended new ignition module and plug replacement, but they said it wouldn?t be a guaranteed fix and that it may need EGR replacement (don?t hear knocking though) or be a burnt valve in the cylinder. No suction out tailpipe, no rotten egg smell (signs of burnt valve). What are the chances of burnt valve in a car with 54K anyway?
Also, my maintenance schedule claims that I don?t need new spark plugs until 100K. Is there anything else this could be such as a dirty injector system, fuel filter, fuel pump, or air filter? Again, overall, the car runs GREAT! Should I just wait and see if the misfire becomes more pronounced so when I take it to a mechanic, they won't be looking for a needle in a haystack?

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?

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 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 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 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?
