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.
View 24 RepliesSo my engine light came on today while I was out so when I got home I plugged in my OBD2 reader and it gave me a P0441 code which in my Haynes manual says "Evaporative emission control system- incorrect purge flow." Before I got my scanner, I had the engine light come on and I took it to VW. It was the same thing last time. I couldn't quite understand the poor explanation given from the VW guy and so now that that code ran again.
View 2 RepliesReally weird thing is going on with my 03 1.8t Jetta, sometimes when I am driving the battery light will come on. It will turn off when I slow down but will turn back on as soon as I accelerate. After a while of this happening I will hear a burst of air and the car will jerk back a little bit then drive perfectly normal. I've looked all over google and posted in a local Euro car group`and haven't found anything.
View 1 RepliesI have a 2005 Jetta 2.0 BEV GLS. I got a code P0302 for misfire on cylinder 2. I am pretty sure it's the Ignition coil. I live in Canada and my autoparts store only has BWD brand. I have read this is a crappy brand.
View 1 Replies2002 Jetta 2.0.... car was jerking when accelerating and check engine light was flashing, severe loss of power and when stopped at lights it would shake and the rpms would drop and go back up... took it in and was told to get the coil pack replaced. One week later new coil pack - check engine light is back on and yesterday same problem (car was idling rough, and severe jerking/flashing check engine light happened again). Took it to autozone to read the code it is giving P0420.... The shop said i might need new plugs and wires, which were replaced with bosch parts one year ago. Any chances these went bad so quickly?
View 3 RepliesI have a Jetta Mk IV, yesterday I went to go drive it and just as I pulled out of the driveway it started running rough, so I pulled back in the driveway and the coolant temperature sensor light came on, then the check engine light. and then it died. Then today I tried starting it, and it will only start and run if I have the gas pedal all the way to the floor, and it runs really rough. Then it will die. I thought maybe the coolant temp sensor since the light came on. I replaced that, and it still does it. I'm leaning towards a head gasket.
View 2 RepliesI'm having with the first startup in the morning. The car turns over fine, but when I accelerate there is a noticeable hesitation. This was only occurring for the first 20 seconds, when I accelerate out of my driveway. Now, it has gotten progressively worse. Still not stalling or anything like that, but it has become more pronounced. I have an APR stage 1+ with a Carbonio intake. Others mention they were experiencing a similar situation. I have tried idling before shutting the car off as well as letting the car sit for 30 seconds after I start her up. Im wondering if I disconnect the battery and allow the ECU to reset might work.
View 24 RepliesI have a 1988 Toyota Camry. I was driving to work this morning, the car was driving fine. After about 10 mile or so, I stopped at a red light, when the light changed the car wouldn't accelerate it seemed to have a really bad hesitation. If i let off the gas it would idle fine, none of the warning lights are on. However, when I give it more gas the car doesn't have any power at all. It has plenty of gas in it and the exhaust has no signs of any oil or water in it. I was thinking it may be a bad fuel filter or a tank of bad gas.
View 6 RepliesWhat are the symptoms of a bad o2 sensor, 2.0.. My son is having some problems with his car hesitating when he gets into the throttle and the only codes we are getting shows bad O2 sensor pre cat.
View 2 RepliesHave 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?
View 5 RepliesI 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?
View 10 RepliesI 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.
View 13 RepliesI 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.
View 2 RepliesI 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?
So,I have a mk4 GTI vr6 . I've got an idle that moves about 25 rmps up and down. As well as the throttle hesitation between 2.000 and 3500 rpms only at mid throttle. Has a kinda new maf. That I cleaned. clean THrottle body kinda new coil pack and wires , new plugs. Tried a lot it all worked but it's still there.
View 11 RepliesI 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)
