Title says it all. I was on my way to grab dinner, stopped at a light and heard it. At first, I thought it was a car next to me. Then it kept on going, and my CEL came on. I pulled over, shut off the car, popped the hood.
Temp normal, no smoke, restarted and watched the engine. Rough idle, and it appears to be bucking. Sounds like belt noise, not sure what is going on..
MY 2003 Santa Fe is fwd with the 3.5 v6. While under normal conditions, the engine lost power and began "chugging" and "bucking". There was also a belt slipping "whine" associated with this problem. The problem continued for about two minutes, then corrected itself, and I was able to drive normally.
View 1 RepliesSo, this past Saturday, I was driving down the road at about 40mph when all of a sudden, the engine started to buck and violently shake the car. I immediately pull off the road and settled on a side street with engine still bucking. When I made the turn, I applied a bit of throttle to get it round and there was essentially no throttle, so I kind of coasted to a stop. It was the strangest thing. I let it sit for 10, turned the key, and the starter turned the engine over only to start bucking again. Immediately turned off the car.
Figured I'd program the car back to stock mode (have APR Stg 1 flash) and give it a shot. Except this time, the starter worked and the engine didn't turn over. Tried a few more time, but got the same result. Starter worked, engine didn't. Fast forward an hour and a half and a flatbed shows up to haul me to the dealer. Called the dealer today to find out they haven't been able to replicate the issue and there's no code. In fact, they actually got it to start and it's been idling for 30 mins. When the tow guy came out, he thought it might have been an issue with the car not getting fuel - which seemed like a possibility. But, the car has a full take of 93 oct in it.
Like I said, APR Stg 1 ecu flash and that's it. Has 31K mi. DSG. Funny thing was, a day before this all happened, I brought it in for a 30K check-up and there weren't any issues.
I have a 2004 gls 1.8t Jetta. It has a straight piped turbo back exhaust, and a stage 2 tune. I recently had a problem with my car starting to rough idle when the engine gets to proper temp. The car starts to idle roughly, and when driving the car will bog down, if I keep my foot on the gas, the car acts like it is coasting and the rpms fall, but at some point the car will shoot off like i floored it. At lower rpms in the 1st and second gear, the car will randomly and periodically start bucking, with the same symptoms. I already replaced my coil packs and spark plugs with a kit off ecs, and when i went to change the spark plugs i had oil on the spark plugs and oil leaking from a bad valve cover gasket, so that was replaced as well. I replaced the fuel filter already.
The MAF sensor was just cleaned and didn't look too dirty. When I unplug the MAF it still idles rough. The fuel pump relay can be heard working properly when the door opens. Another problem that sometimes occurs on cold start is if I don't wait long enough for the pump to activate or sometime right after it starts, the car will start partly then stall out. When driving and the car is bucking the exhaust gives rich fuel smell. Also when 2 stepping in the car (which I don't do very often), the CEL starts to blink and the car misfires and drives rough. I figure since I don't have many parts on it yet I probably shouldn't do it anyway so I don't blow up the engine.
I've had a weird problem pop up within the past few weeks. My engine seems to have a noticeable whine above 4000 RPMs. It sounds almost like a supercharger whine, but my engine is completely stock. Possible problems I found online include exhaust leak, vacuum leak or tensioner issue for the belts.
Another issue I have had is that whenever shifting into second gear, I have some difficulty getting it into second gear. It makes a scraping sound as though the clutch is not disengaged all the way. On occasion, I have also had the shifter kind of pop second gear out when continuing onto third or even feel like it is rejecting second gear sometimes. A friend of mine told me that the scraping sound is normal and, "that's just how manuals are." Doesn't seem normal to me especially since it is every time I shift to second gear.
I have an 05 jetta 2.0 and I had a loud whine on passenger side of engine. I removed serpentine belt and ran engine briefly and noise was still there. Figured it was water pump or tensioner. and when I was changing timing belt, tension, and water pump I found it was the timing belt itself that was whining. It was OEM original belt with 140,000 miles on it. The belt was in very good shape no tears just used looking. Now engine is very quiet.
View 1 RepliesSo I replaced the engine and trans engine mounts on my 2004 R32 today. After I got done and drove it there was some serious vibration and gear whine. It also seemed like I wasn't able to transfer all the power to the wheels, it was definitely slower to accelerate. Did something go out of alignment?
View 2 RepliesSo recently my car has been starting to over heat. not to the extreme but the temp needle is going past the middle. only happens when stuck in traffic but as soon as I start going it goes back down.
As far as iv noticed only thing getting me puzzled is my fans are not running when running and starting to overheat. they run when I shut the car off though. The radiator is less then a year old. fresh oil change and the coolant is fine
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 10 RepliesI just installed a new pair of PSS10 coilovers on the R today and everything is running great, except a creaking noise I am hearing under extreme turns. If I am going slow, I can whip the wheel all the way to one direction and hear the creaking noise, or if I am going around a longer corner at higher speeds, I hear it as well. I've taken the wheels off and checked, everything is tightened.
Based on the searching, most are complaints of similar sounds but in straight lines. This is only when turning. There are only 20k miles on the car, but that includes 7 weekends of HPD events. So worn/dry bushings or joints was my first thought.
I 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.
just picked up this 99 Jetta with about 150,000 miles and while driving all of a sudden i had extreme power loss, shaking and shuddering, and the engine light came on. My code reader found multiple random misfires cylinder 1 and 4 codes P0300, P0301, and P0304.
View 7 Replies97 Accord Lx - 215k miles - 4 cyl. - regular maintenance. It's been my daily driver for over 5 years and been running perfectly.
Yesterday I drove the 35 miles from work back to my town but before going home stopped to visit someone for about an hour. When I came out to leave I noticed a larger than normal amount of fluid in the drive. I just thought it was condensation from the AC and that it was more because it was extremely hot yesterday (100+).
When I got within 2 miles of the house the 1st thing was that the AC was not blowing as cold. I turned it off. Then the engine seemed to "pulse" with loss of power, and the temperature gauge was maxed out. As I pulled into the driveway the engine light and oil pressure light came on.
After it cooled down I checked and the coolant was a little low, so I topped it off. The oil was really low and I added three quarts to bring it to full.
This morning I started it up and let it idle while I finished getting ready (5-10 minutes) and the temp gauge was about 1/3rd of the way up (where it normally is). It sounded, felt, and drove as normal but after a mile or so the gauge was climbing extremely fast so I turned around and took it back home.
What it might be? Water pump?
Was driving my 1992, 3.0 and all of a sudden noticed temperature gauge go to extreme hot, steam from hood and engine stalls. Upon inspection, the heater hose blew out, and van does not start even the next day, plus I think the starter sound different (faster). Saw spark at plug wire, smell gas, and did a quick compression with my thumb on #1, and felt air.
Towed it to the mechanic and within 5-10 minutes told me it was a cracked engine, I was not there but he stated he did a compression test. Is he correct, or can it be a timing chain problem?
[URL] .... I reviewed the thread but my issues happened all throughout my drive back.
The car started to "buck" between 500-1000 rpm while in 1st gear. Randomly in 5-6th gear it did the same thing ( Car felt like it wanted to shut off in the middle of driving). I also smelled a horrible petrol scent when stopped at a red light. The car never totally died, but it felt like it wanted to the whole time.
What could be the issues? Coil Packs? Bad Gas? Belts? Battery?
My car just had an oil change with amsoil and new vw oil filter. New spark plugs in the summer, fuel filter changed, and rear diff fluid changed.
So me wife has put on about 7000 miles on her new tdi. It's a dsg, 2012. We brought it in for some warranty work and oil change at 600miles.
She is having bucking forward and back issues in the morning and after the car has sat for a while. When you go to accelerate light throttle it literally jerks forward and back and moves you in your chair when shifting first to second.
Dealer said no codes no updates nothing. I know the dsg is clunky normally but it literally jerks us back and forth in the seat 2 to 3 times or more.
Also when on the highway it surges up and down when cruising 70 to 75 like wind is blowing the car with steady throttle.
I told dealer last visit to reset the dsg gearbox as my wife did 70%traffic driving the first 4000miles. Now it's 90% highway.
My 2003 Camry with the 2.4 engine sometime bucks when you let off on the accelerator pedal. Sometimes when you just lightly back off on the pedal it feels as if the car is braking slightly. I do not have the problem all of the time and I'm not getting any OBD fault codes. The car drives fine except for this problem. I am thinking maybe the accelerator pedal sensor or maybe the mass air flow sensor may be the cause.
View 14 RepliesBuddy of mine woke up with a GLI that runs like this. Stage 2 Uni, cold air, 3 inch turbo back. [URL] ....
View 2 Replies 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?
Started my car (02 with a 2.0) this morning and as I pulled away the EPC light came on and the car lost power, almost stalling. I kept on going, and then the check engine light came on.
Got to a stop sign and it died on me. Battery light came on at this time as well. Started back up no problem but idled rough and kept dying. Just kept restarting and moving bit by bit until I could get home. EPC and check engine stayed on through all of this.
I also noticed that it would buck like crazy around 3000 rpm and not increase past that point. What could be going on here? I'm going to pull codes when I get home.
