Golf - Volkswagen - Misfire :: 2003 - Engine Started Shuddering?
My engine started shuddering rather considerably a few days ago, seems to be misfiring. Happens both while idling and accelerating. Thought it could be a bad spark plug, and was prepared to replace them. Which is doable, but not easy, considering they're not very accessible with this particular engine. But when I lifted the plastic cover off the engine to take a look, I noticed this tube (circled in picture) had been worn away considerably in one spot. In fact, it's barely attached.
Now I'm no expert, but I've read that a leaking or disconnected vacuum hose can cause exactly the type of issue I'm experiencing. I'm wondering if the object pictured is in fact a vacuum tube. Might that be the issue? If so, how easy would it be to repair it myself? I'm not very experienced with making my own repairs, but I'm good with a set of tools, as long as I have instructions.
Toyota - Corolla :: 1995 - Started Shuddering While Going Up Hills?
95 corolla 277k miles. 4 hours into a long trip went over a huge bump and the shocks seemed to "bottom out". Like they compressed as much as they could. Pulled over half hour later for a break.
After that drove rest of way home. Car started shuddering and slowing down going up a hill. Had to floor it just to get it to be 60 mph. Hill wasn't that steep. Seemed to do ok on flat parts.
Was a little low on gas so pulled over to fill up. Noticed car idled very roughly felt like it was going to stall while pulling into gas station.
Gas cap was a little loose. Didn't hear the whoosh of the vacuum you usually hear when undoing the gas cap either.
After that it seemed to be a little better going up hills. I drove it home, and a day later drove it and it seemed to go up hills ok.
It still idles very weirdly, roughly and like it's about to stall. While driving it sounds ok.
I was thinking fuel pump but now i'm not sure. It might be related to the gas cap, maybe the bump loosened it.

I drive a 2001 VW Jetta and have had many issues with this car but have had this particular issue many times. It starts when all of a sudden my car feels like it's going to stall when idling. When I go to drive it in this state the car has difficulty excelerating, bucking and sputtering (like the engine isn't getting enough fuel) and the engine light comes on. I have taken it to many shops and they usually replace an oxygen sensor saying that it is clogged etc. I have also had a couple of tune-ups because of it but after about a year the issue comes back and I shell out more money. I was told by one mechanic to use only super gasoline and that it should prevent it from happening again which I did and it held it off from happening again to about a year and a half but now it's back.

I have a 2001 mk4 golf 1.8T, tonight I was driving and all of the sudden the gear changes started clunking really rough ( it's an automatic) and then it would pulse for power only give it to me at random not when I gave it gas, coming to the next stop sign I pushed the accelerator to go and for the first 3 seconds nothing happened until it jumped in revs spinning tires and shooting me forward, so I shut off all the electronics in my car which seemed to work with the not getting power issue but when I finally got to where I was going it now won't turn over, you turn the key you hear the starter try but that's it it just won't turn over, there's no check engine light and I already have a call into my mechanic.

1995 vw Jetta 110K miles.. My car has a hard time starting in the mornings or when it sits idly for a while (when I park overnight) . On any bright and sunny day, it's like the car is brand new - starts with no problems at all. Tried several mechanics and none of them have been able to diagnose the problem. To make it simple, cold outside - car will not start, warm/hot outside car will start.

I was driving on the highway in my 2001 jetta (332000 km) on the cruise control yesterday and suddenly it just started slowing down and stopped. Putting my feet in the gas did nothing . Before stopping completely the battery light came on. After won't start anymore, just making a sound like it is trying but turn in the butter. To be honest the check engine has been on for a while but we are pretty sure that is the glow plugs because it is a recurrent problem... Nothing else light up and there was no sound or smoke.
View 3 RepliesAccent MC (2006-11) :: Bucking And Shuddering When Warmed Up
After almost an entire year of trouble-free running (with the exception of replacing a ground strap), my 2009 accent decided to start bucking and shuddering again. It only does this when warmed up, runs perfect cold. In the last 16 months, I've replaced the plugs, coils, battery, PCV valve, and ground strap. Car starts with zero hesitation.
Strong battery and starter, consistent output from alternator. After @5 miles, the car stumbles on acceleration, and idles sporadically. While looking at it tonight, I noticed a few exhaust brackets under the car had broken, and the flex section of the intermediate pipe had torn open. Could this presumed exhaust leak be causing the crap running performance?
(My "exhausted" brain thought it could cause the O2 sensor to misinform the ECM, resulting in the P0300 code I pulled...).
Jetta - Volkswagen :: Idles High - Gas Smell When Car Gets Started
I have a 2003 Jetta. After it runs for awhile, if I have to shut it off and start it back up - I have to pump the gas to get it started and it idles high and gets flooded. I can smell gas after it gets started. A mechanic already replaced the ignition coil, which wasn't the problem at all.

View 4 RepliesGolf IV / Jetta IV :: MK4 GLS 2.0 Shuddering When Drive In Reverse
I bought a MK4 GLS 2.0 5 spd with 200,000km on it back in february, It currently has 208,000km on it.
Whenever I drive in reverse, I get this loud shuddering/rattling noise with a slight vibration. I've noticed that it is louder from a stop and when the clutch it partially depressed accelerating,but pretty much goes away when the clutch is let out or when coasting.
It is sounds like it is coming from behind the front seats to the rear of the car. It almost sounds like the rear shock mounts are rattling. I also sometimes still here a slight knock, similar to the sound of worn sway bar bushings, but replaced those a few weeks ago.
I also get the same knock whenever I screw up a shift and the engine moves. I also considered and engine or transmission mount but i don't really get any vibration through the steering wheel other than a small amount which could be attributed to the poly dog bone bushings.
About two months ago but I replaced the RR shock mount with a new one. The old one looked fine. I replaced the RL shock mount with the one that I removed from the RR side.
Changing the shock mounts made no difference but I noticed that I could easily compress the RL rear shock with my hand. Could worn rear shocks be causing this noise/vibration? I've searched but I can't find an explanation besides the shock mounts.
I have replaced a few suspension components in the last few months:
-rear beam bushings in august
-front sway bar bushings a few weeks ago
-RR rear shock mount (new)
-RL rear shock mount (used from other side, but looked fine and replacing it made no difference)
-energy suspension poly dog bone bushings about six months ago
I don't think the car was really maintained that well due to it having original sway bar bushings and having tires that were worn very unevenly due to the rear beam bushings when I got it.
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...
Ford F-150 (2004-2008) :: 2005 - Occasional Bucking / Shuddering When Slow Down From Highway Speed To About 30mph
I have a new to me 2005 F150 SuperCab Lariat 4x4 with 155,000 miles on it. About a week ago I replaced the from passenger hub assembly and half shaft (torn boot). When doing that, I noticed that the IWE actuator was not working right (would not compress evenly). When taking that off, there was a bunch of rust that came out of the vacuum line ports. It started moving freely after cleaning all of that out that I could (I will be replacing it soon). I assembled everything back together and all seemed OK mechanically.
I also scanned the truck and saw the code for a bad IWE solenoid so that is being replaced tonight. I also have not checked the drivers side yet.
So...now that I have done all of that, the truck started occasionally bucking/shuddering when I slow down from highway speed to about 30mph and lightly accelerate again. It does not do it every time though. There is no grinding/whining noises either. Could this be caused by the IWE system somehow? Maybe slowing losing vacuum and having one engage and the other disengaged?
Golf IV / Jetta IV :: Hard Bucking At Partial Throttle
Buddy of mine woke up with a GLI that runs like this. Stage 2 Uni, cold air, 3 inch turbo back. [URL] ....
View 2 RepliesGolf IV / Jetta IV :: 2013 - Bucking / Hesitation At Low RPM And 5% Throttle
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?
Golf IV / Jetta IV :: EPC Light And Bucking / Loss Of Power
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.
Golf - Volkswagen :: 1993 - Suddenly Bogs Down And Goes Sluggish Like Not Getting Gas Or Firing Correctly
1993 Golf GL III, automatic: Engine size: 2.0 Date on door 5/1993
I have an intermittent problem, in the morning my car will start fine, idle fine and drive well for about six blocks, but then it suddenly bogs down and goes sluggish like it is not getting gas or not firing correctly. It has not stalled completely, it just bogs down and giving it gas does not do much. I can barely coax the car to my destination about a mile away.
The weird part: A few hours later when I leave this location my car runs fine, starts fine, drives fine and I have no problems the rest of the day. Thus, I only have this problem in the morning, otherwise the car runs great.
Question: Could there be a sensor that is reading incorrectly in the morning, but is fine after it warms up? Perhaps the sensor is messing up the air/gas mixture.
NOTE: My check engine light is on, but I have not figured out how to pull the codes. In the middle console, above the ash tray behind two unused button panels, I have two diagnostic connectors, one black and one white (see photo). I think they may be 2x2 connectors, perhaps OBD1, but I am not sure.
* I have heard a jumper cable can be used to get the codes to blink, but I have not found any documentation to confirm that for this year and model.
* I am also not sure if an OBD2 scanner could read this codes if I use an 16 pin adapter.
Pull codes, either using a jumper or scanner, My local auto parts stores will not pull the codes.
Golf - Volkswagen :: 1995 - When Accelerate, Revolutions Goes Up But Speed Stays Same
I got an automatic VW Golf 3 1995 75ps for my wife, Basically it was a gift, the car is in OK conditions, motor works very decent and for my own amusement the thing actually drives great! The only problem is in 3rd gear, the car change between gears clean and very tight, the problem is when the car accelerates the revolutions goes up buuuut the speed stays basically the same, until I put my foot out of the pedal and reaccelerate, then slowly it works fine but as soon as I put some power on it, it slip, very frustratingly BTW! There is no worrying noise, no smoke, no leak, I haven´t measure the ATF mainly because it is impossible in this car! It is supposed to stay closed forever! (?). My main question is if the ATF can be related with this issue or is it other component of the Transmission? Second question is if the ATF is not related then what can it be?
View 13 RepliesGolf IV / Jetta IV :: VR6 - Backfiring / Bucking Occur From 2300 - 5500 RPMs
I have a 2000 Jetta VR6 12v. I'm having an issue with backfiring. Also, I am having a severe issue with bucking. Sometimes it will not happen at all, and when it does happen it can occur from 2300-5500 RPMs. No matter how hard or soft I am on the throttle, it will hit this point, different everytime, and the throttle will cut out, then pick up, then cut out, then pick up.
Now, I know my MAF is throwing a few codes. But it was throwing codes for a month before this started, maybe longer,and the only symptoms were backfiring and a little lag at startup. However, the same night my issue began, I also developed a coolant leak. Upon inspection, the coolant leak path was traveling directly over my CKP sensor where it connects to the engine block, which also began throwing a code. The car starts fine, idles fine, and never stalls or dies. So my options here are replace the MAF if that seems likely to be the issue, or to attempt using liquid electrical tape to prevent the leak from hitting my CKP sensor.
