Golf IV / Jetta IV :: 2001 - Rough Idle / Stumble And Die
Just bought a 2.0l 2001 golf four door. the previous owner had the car for only a short time. They claimed the CEL came on and the code was for the MAF. He cleaned it and when I test drove the car there was no light or sign of any issues with how the car ran. Today while figuring out why the alarm kept going off(battery died in key fob and i replaced them), it began idling rough. It had just started to rain as well. From what i could find from older thread is it could still be the MAF, TCV/ISV, or O2 sensor. Is there any good way to diagnose without a vag-com cable. Mine wont update its firmware and i'm screwed at the moment in terms of gathering info on the problem.

2001 VW Jetta 1.8t automatic.
Transmission has a hard time going into 1st and reverse. Also some times hits hard going into third. I have a CEL for a vehicle speed sensor? Was wondering if it's not the VSS but maybe one of the other tranny sensors?
Separate question. Same car has a rough idle issue. Occasionally stalls but intermittently runs normal always has a low idle around 600 rpm. I have a code for an injector on cylinder three.
VSS code : P0725 - engine speed sensor circuit malfunction
Injector code : P0203 - injector circuit open cyl 3
Golf IV / Jetta IV :: 2001 - Rough Idle And Black Smoke Coming Out Of Tailpipe?
I got my 2.0 turbo project up and running. no CEL but i did have a bad o2 code but it was erased and didn't come back.
Not only is it rough idle and smoking out the exhaust but i am also getting smoke out of my catch can vent.
The smoke looks black coming out of the tailpipe but little blue after it gets out a ways from the car. Where to look??
I did just replace a piston and install a head gasket spacer. I don't know if that could be causing it some and it will go away with some driving or what?
I have not taken it out on the road as I have some brake work to finish. so mostly it idled.
Here is a link to a video on what the car is doing : [URL] .....
Its a 01 engine code....
Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 Rough Idle / Shaking When Press Accelerator And RPM Go Above 2K
2001 f250 7.3L, 289,000 miles, changed the IPR and ICP, noticed the EBP tube was in two pieces. Would this cause the rough idle and shaking? IT started running rough and would die after a mile or two. Would have to wait 30 minutes before it would start again. That is when a buddy told me to change the IPR and ICP the ICP plug was covered in oil as well as the top of the ICP. So I changed the wiring plug as well. I originally cleaned and changed O-rings on IPR but then it wouldn't start, bought a new IPR and started but runs rough. I just started it with EBP tube removed and sensor unplugged. Idling rough when I press accelerator and RPM go above 2K it levels off pouring black smoke everywhere.

I have a 2003 santa fe I just replaced the cat. in it because it was running so poorly. Now that I've replaced the cat it seems to be worse. The car idles real rough, and cant get it to go over 2000 rpms. No engine light. Had the codes checked and all came out fine. I pulled out the plugs and replaced with new. The car in park ran great until I put it in gear then went back to the same no power, rough idle and cant get more than 2000rpm with out a stall. Stalls but dose not die. Disconnected the pre o2 sensor no change.

We are at 120K miles. The vehicle runs fine most of the time, but every once in 10-15 starts, it will rough idle or stall after a short warm up time when my wife stops at an intersection. Once she restarts it, it runs fine.
I have changed the spark plugs and wires, the fuel pump, the crankshaft position sensor (was fried) and after consulting this forum, I checked the fuel pressure regulator and the diaphragm is not leaking.
I was able to recreate the rough idle and the CEL on the dash, but my two OBDII readers said there were no codes And the bluetooth reader I am using is indicating that the following tests are not completing: Fuel System, Catalyst, Evaporative System and Oxygen Senors.
The dash CEL resets itself upon restart and does not light until the symptoms return.
After reading the Haynes Repair Manual, I am wondering about the Evaporative Emissions Control (EVAP) system? But I don't want to lead the troubleshooting.
We bought the vehicle at 60K miles and it has been mostly reliable.
Golf IV / Jetta IV :: Air Conditioning Almost Stalls At Idle
I had just picked my car up from the shop after getting a new 3" downpipe installed (welded to stock cat) and attached to stock catback exhaust. I mention this because I never had this problem before and have already had installed a TIP, boost hose kit, DV, larger intercooler, and breather hose kit, all for a Unitronic Stage 2 tune.
So I go to turn on the A/C and the idle drops to about 400 rpm, almost stalls, interior shudders, vacuum jumps from about 20 to 10 as the engine revs itself a bit, and then it settles back out and the car runs fine (awesome with the new tune) and A/c works great. I have used the A/C a bit since getting all other upgrades done and never had a problem, or I didn't notice, but I'm wondering why a new downpipe would make a difference. I tried turning it on and off a few more times and the same things happened at idle, but after that initial dip and near-stall the engine was just fine around town and on the highway.
Golf IV / Jetta IV :: 2001 - Car Stalls Whenever The Gas Gets To 1 / 4 Tank
This has been happening for awhile now, but whenever the gas gets to 1/4 tank and below (about 2 ticks from the red tick on the gauge) the car will stall for about 3 seconds then come back to life. If it happens while I'm stopped it will completely die and I'll have to restart it.

I have a 1987 automatic Nissan Sentra XE- two barrel carburetor, mileage 212,880. The car has one major problem that is going to get me hit driving it in rush hour. Most mechanics will not touch the car due to being carburetor.
Let me explain: the car idles real rough at times, hesitates at stop signs and red lights, about stalls out on me when I press the gas pedal to go or when I start to make a left or right turn. However, other times the car has little to no hesitation and idles perfectly. I have not been able to come up with a good a pattern with this problem.
I have replaced, fuel pump & filter, spark plug wires, coil, distributor, ecu computer, ran sea foam through the fuel system and have replaced many vacuum hoses.
Golf IV / Jetta IV :: 2001 - Stalls While Driving Then Picks Up Again
The car starts well every time even though the revs go up then down for just two seconds before stabilizing at normal rev count. Sometimes while driving the car would just stall and loose power even though my foot will still be on the accelerator, if I pump the accelerator it will wake up and move on nicely like nothing ever happened. I've had this problem for the past two months now and it happens atleast 5 - 6 times a week randomly. the problems is beginning to get worse. The car has an automatic transmission. I've changed the fuel filter and air filter only in the last 20000kms. the MAF is ok because when i unplug it the car switches off and won't start again. every time i open the hood and rev the car a bit i can hear what sem to be huge suction of air somewhere next to the throttle body.

Golf IV / Jetta IV :: 2001 1.8T Does Not Stay On / Stalls Out On Cold Start
When the weather gets cold, (lower than 45 deg. F) my Jetta does not want to stay running. It turns over and starts just fine but it does not like to stay on. When I turn the key to the #2 position I can hear the fuel pump fire up and pressurize the system. I always attempt to start it after that, and after 1-2 seconds of running, it seems like it chokes itself out. I have the new coolant temp. sensor (green top), my MAF has been replaced, all spark plugs are new with the correct gap (approx. .030"), new air filter, I run 93 octane fuel.
The worst part is, once the car is warmed up (After forcing it fuel and starting it over, and over, and over again) it runs awesome! I have had this problem since I bought the car (about 2 years ago). The owner told me about it and mentioned that he has never been able to figure it out either (trips to the dealer included). I have been dealing with it for 2 years, but it is getting much worse. Over the past 2 days I have not been able to get my car to stay on long enough to get it to move.
Golf IV / Jetta IV :: 2001 VR6 Engine Idles Sometimes At 600 Rpm But Drops And Nearly Stalls After Revving
I have an '01 gti glx that I just swapped a motor into. I got the motor out of an '01 jetta glx, exact match AFP engine code.
I get cylinder 2 misfires mostly (high number) but I also get 5 and 6 intermittently as well as a P0300 code.
Sometimes I also need to hold the gas down just to get it to start even after the crank sensor.
The engine idles sometimes at 600 rpm but drops and nearly stalls after revving at all.
What I've tried so far:
working cam sensor from my old vr
brand new crank sensor
brand ned wires/plugs
new fuel filter
swapped injectors of misfiring cylinders from old motor
lined up the timing 3 times now and its still perfect
I know the coil pack works because it was on my old motor, which ran fine, just leaked oil.
Golf IV / Jetta IV :: Rough Idle Between 600 - 800 RPMs
My golf 2.0 vw isn't doing so good right now. It has 227000 miles on it. It has been driving great, and then last week it started to idle rough. It idles between 600-800 rpms. it fluctuates between 600-800 rpms. It had the check engine light on before this happened i was told by my brother that it was an 02 sensor. I had it checked for what is causing the engine light to come on today at o Rileys, and it came up with 11 codes. Some of the codes where 02 sensors, it was running to rich, needed a new computer, evaps system, fuel pump, fuses, coil pack, spark plugs, It shakes when you sit in it when it is idling like not a bad shake but a small one you cal feel, l'm including a video of it running.

2001 vw cabrio 2.0 .. The car starts and stalls BUT only if you give it gas. I replaced the throttle body and did the throttle body alignment using vas-pc , no problems at idle but as soon as i give i gas it dies, and it seems to die quicker at higher temperatures. When it dies i get codes P0121 and P1570 i clear the code , do the alignment , and same thing happens over again. I also replaced distributor , crank sensor, maf sensor , spark plugs, wires , rotor, tried different pcm reprogrammed, no vacuum leaks, the only thing i can think of now is the ecm relay? but its missing so is it using the fuel pump relay ?
View 3 RepliesGolf IV / Jetta IV :: Assuming Car Clogged Because Of Rough Idle
After putting on a o2 spacer my CEL cleared. I finally got some downtime so I parked the car in the garage to chase electrical gremlins, do the timing belt, and replace the downpipe and catalytic converter. Lately it's been sounding like I have quite the exhaust leak so that spurred me into doing a little quicker. Long story short I got the cat out and after looking inside of it I see this .
The inside of the cat is completely bare, not even a remnant of any form of honeycomb. So was this a hollowed out cat or did everything deteriorate and blowout. I was assuming my cat was clogged because of my rough idle lately... but looks like I was dead wrong.
Now for additional info.

I can't currently check my codes because the OBD2 isn't reading/connecting, but that's not related.
Golf IV / Jetta IV :: Rough Idle - Smoothes Out Only At About 600 RPMs
The problems seems to be getting progressively worse, it has a rough idle and when it smooths out is only at about 600 rpms and still sounds strange. Also, I am running extremely rich, blows flames quite often and in OCMD I went 100 miles on a half tank. Car is stage 1 unitonic with sai and evap deleted. I changed the maf and that didn't change anything. I was searching for vacuum leaks yesterday and noticed that one of the vacuum caps I have on the bottom of the intake manifold was dried out so I took it off so i could put my finger over it and see if it ran better, when the cap was off it ran great but when I put my finger over it it would go back to an awful idle Now when I come to a stop it will sometimes drop the rpm so low that it shuts off, when I am driving you can't tell a difference.
