Golf IV / Jetta IV :: 2002 GLS 2.0 - Misfire In Rain Only And Check Engine Light Flashes

My 2002 Jetta GLS 2.0 is misfiring only when it rains out. I go to start the car and the car idles extremely rough and seems like it wants to die. I checked out the codes for the check engine light and I got misfire codes p0304 and p0300. Which is a general misfire detected, and misfire on cylinder 4. I noticed that when I misted the alternator during the day around 70 degrees with the car running the car would misfire and almost die out. I know you are not supposed to get the alternator wet, but keep in mind i did not soak it I misted water on it. I misted the coil pack and nothing happened. I replaced the spark plugs and wires a few days ago. But as soon as it rains my car does not idle right and the check engine light flashes.

Golf IV / Jetta IV :: 2001 VR6 GTI - Idles On 3 Or 4 Cylinders / Runs Rough

2001 VR6 GTI....

Already done:

Replaced the coil pack and plugs

Measured resistance of plug wires (all at about 6K Ohm)

Replaced front O2 sensor

Replaced purge solenoid valve

Replaced coolant temp sensor

Replaced fuel filter

Replaced fuel pressure regulator

Replaced MAF sensor

Cleaned the throttle body

Cleaned the throttle position sensor

Ran a tank of seafoam treatment (injectors were new 6 mos ago.)

Checked running voltage of battery

It was smoking and stinking bad with a rich mixture. It improved with the MAF change but still runs like a farm tractor. Now it idles on 3 or 4 cylinders, runs rough through 3000 RPM then runs cleaner at above 3000 RPM, but only at light throttle. CEL is either on or flashing when driving.

Don't know what to do next - nice car not fun to drive like this. What this could be and how to test it?

Golf IV / Jetta IV :: 2000 - Excessive Blue Smoke And Screeching On Start Up - Runs Rough

I got 2000 tdi with 270000km on it and have a few issues with it and am looking for some information before i start doing some work to it.

First problem excessive blue smoke on start up also runs ruff tell it warms up.

Second the is a screeching noise on start up some times. happens most of the time when the car is cold.

Third sounds like something is dragging or rattling but i have checked and there is i can see.

Fourth when the clutch is in and the brake is on the car runs ruff at idle. i think it has something to do with vacuum used for the brake booster but not sure.

Golf IV / Jetta IV :: 2002 JTI 1.8t ECM Replaced - Car Turns Over / Runs Then Dies

My friends car suddenly quit running while he was on a trip, he went through the carwash and as he pulled out the car died. He had it towed to a shop and they charged him $400 to run a few tests and replace the fuel pump relay thinking it would fix the problem, obviously didn't or i wouldn't be typing this. At this point the car cranks but won't start.

This is what the sheet from the shop says, "retest through PCM to locate problem. Ran diagnostics per flow chart. all power, grounds and G28 engine speed spensor output to ECM test good excepting pin T121/86, wire color Lilac/yellow. Signal between camshaft position sensor to ecm. No voltage signal recommend replace PCM and RETEST."

I've put a used ecm (ecu? i've read both terms used) in and the car cranks, starts, gets to idle and dies. If i give it gas after it starts it'll rev up once, then die. I'll call it progress, but i want this damn car out of my driveway.

Golf IV / Jetta IV :: 2002 1.8T - Insufficient Power / Idle Little Rough

02 Jetta GLS ... 1.8 Liter Turbo ... 5 speed manual

Threw a lot of codes I don't know the #s but I can get them tomorrow, but I know there was a throttle pedal sensor, cam sensor, MAF, turbo, and a computer one.

I've had the car 2 weeks and its driven fine every day until today I backed out of my drive way after doing some driving earlier in the day and popped it into first and she fell on her face, no power rpm's were near 300. shut it off start it back up idles a little rough and I have a traction control light CEL and EPC lights all on. when I first take off it chugs and is hard to even get going and then it takes miles to get up to speed. I can put the pedal to the metal and my rpms barely budge and the car ever so slowly gains speed, she eventually will top out around 70. but that's after quite a stretch.

This happened one other time and after a few minutes everything went back to normal for nearly a week , this time no such luck.

Possibilities to shoot down maybe?

-fuel filter/system
-Cat. converter
-MAF sensor
-Coil packs
-computer something??
-throttle body
-turbo
-electrical

Golf IV / Jetta IV :: 2002 - Running Rough Then Stalled After Starting

So the Jetta started running rough, then stalled after starting. Couldn't drive it home so I had to tow it. Got to the house and read codes. It gave me P0135, P0171, and P0321. I researched and saw that the only code of these three whose symptoms included stalling was P0321, so I replaced the Crankshaft Position sensor. Tried starting it, and it wouldn't start at all. I kept at it for a while thinking it would catch, but after 5 minutes the battery was too low to crank. I tested the old crankshaft sensor, and had resistance of about 900 ohms, so it was in range. For giggles, I pulled the new one and checked it, also in range. I put one of them back in, and proceeded to scratch my head. Charged the battery up, and now not sure what to do. I need to do a very close hose inspection, but there are no obvious tears or breaks.

Golf IV / Jetta IV :: 2002 - EPC And Traction Control Light Came On / Rough Idle

2002 GTI 1.8t (No Tune) 95k

Car becomes harder to start before the problem starts occurring. When the car is started, the idle will rise above what it normally does (750rpm) to 1200-1300rpms and drop back down and raise back up again. Its like its constantly revving itself, this continues the whole time the gas is not being applied. With this comes the EPC light, the Traction Control light and a hardness to the brake pedal (as if the brake booster hose is disconnected or its not getting its vacuum assist, very hard to brake when rpms are at idle). Sometimes im able to boost but most of the time, i am not able to exceed 2lbs of boost. Limp Mode? This has happened before about 5k ago.

I sacked up and got it diagnosed and it turned out to be the Throttle Body, Crankshaft position sensor and the brake booster hose. All at the same time, which is weird. But all those items were replaced by me and the car ran fantastic. until now. This will be the 3rd throttle body put in since the car came off the line. it seems like thats the problem since the brake booster hose is fed vacuum to the throttle body? But i would love second or third opinion before money is spent. If it is the throttle body, what could make this unit go out so systematically and slowly? If it was wiring then you would thing itd kill the part quicker than 5-10k miles. I will post the CEL codes when i can get one to come on.

Dodge - Dakota :: 2002 - Runs Rough - Won't Restart - Die After Rev

I have a 02 Dodge Dakota 4.7 liter that is killing me. No codes and no check engine light. From a cold start it starts fine but then runs rough. If I let it run for a few minutes, turn it off and try to restart it, it is very hard to start. Also, if I have it running and rev the engine above 3k rpm and let go of the gas it dies. It will idle without holding the gas pedal down but will die after a rev. Fuel pressure and volume are right in spec. Have good compression, spark and injector pulse on all cylinders. I thought maybe a crank or cam position sensor, but either of those would usually throw some type of code. I thought IAC but it seems to be functioning properly.

Dodge - Dakota :: 2002 - Runs Rough For The First Mile Then Clears Up

My 2002 Dakota with a 3.9 (200,000 miles)has a problem that I cannot seem to cure.When I start the engine it never hesitates....it starts without a problem. No excess cranking...it fires up as it always did.It does run a bit rough as if ONE cylinder is missing every few revolutions. If I let it idle in the driveway for five minutes it will clear up and run fine. But if I take off right away the following will happen.I put it in gear (automatic) and for the first mile or two it runs as though the plug wires (More than one) are wet and arcing. I can barely get above 25mph. it will spit and sputter for that first mile or two.

Then suddenly it will clear up and surge....probably because I have loaded the system with excess fuel......and after it clears up , I have no other problems with it weather I'm on a long trip or a short one. If I stop for more than 15minutes, I have to go thru all this again.I've had vehicles that acted like this after a hard rain because the plug wires were old and arcing...that's why I use that as a description.I also noticed that the other day right at the end of a big downpour it took at least 5 miles to clear up.

Before this rainstorm I had replaced the plugs, wires, rotor and cap, while inside the shop so everything should have been bone dry except for all the humidity from the storm. After starting I checked for any arcing while in the dark shop and even moved a few wires that were touching and no arcing was seen from the cap, wires or coil. I also changed out all those parts 6 months ago when I did a major tune up, but it ran fine untill about two months ago.

When this started two months ago is was just a rare occurrence and my mechanic thought that I had gotten some gas with water in it. He had me run a few bottles of injector cleaner it the next few fill-ups and I've run a few bottles of heet through it also. In the last two weeks it has been doing this every time I start up. When this did start showing up it would show a code of a random misfire and the engine light would come on even though I felt no signs of a misfire myself. The light would stay on for a day or two then go back off. A few days later it was back on.I thought that I fixed the problem because the light stayed off for a month.

So it has been only the last two weeks that it bucks and kicks so bad at a startup, but you would think that an engine misfire would show up and the engine light come on. By the way the light does work. Now, I never get a engine light on, and he found no codes in the history. I have my own scanner, but his can do so much more. I never find any codes also. My mechanic ran some diagnostic's and found an up-stream 0,2 sensor bad so we replaced that.

Yesterday I dropped the tank, pulled the pump and cleaned the tank real good. The only filter is the sock on the pump and that was clean. I refilled with fresh gas and I still have the same problem. So I think that we can eliminate water in the fuel, plugs, wires, rotor, and cap. My next thought is the cam sensor in the distributor.

LS / MKZ :: 2002 Lincoln Idles Rough On Cold Mornings But Runs Fine

The car idles rough on cold mornings but runs fine. It will stall while idling but starts back easily. I am getting a 1131 and a 1151 code with my scanner along with 0300 and lean bank 1 codes. I started having these problems after I had to remove the upper intake to replace coil packs. I was getting egr code and had an egr port completely block off but cleaned that out and no longer get the egr codes. Spraying carb cleaner around the engine I get a very slight bump in rpm around a couple of the intake ports could that be my problem or should I look deeper?

Ford 7.3L Power Stroke (1999-2003) :: 2002 F250 Runs Rough When Cold

I have my 2002 Ford F250 Powerstroke. 175,000 original miles by me and only me. SCT, MBRP, Howes or Stanandyne almost always. Runs like new. It starts rough if I don't plug it in. Even on 50 degree days. Then it levels off and runs perfectly. If I plug the truck in I can drive off immediately with perfect operation of motor. I just went 1500 miles. Pulling a car hauler with car. NP at all.

New Glow Plugs, GPR "Yes it works", IPR, New Harness, Buzz Test shows it's fine, New #8 injector last year, New O rings HPOP. My buddy who is a PStroke guy said this trucks runs too perfect for it to be injectors. He recommends seals for the injectors. What does this mean. Or what else can it be. Where should I start.

Ford 7.3L Power Stroke (1999-2003) :: 2002 - Runs Rough And Stalls After Half Mile?

Here's what I'm dealing with. Took the truck on a 1500 mile trip with no issues. Got home and started it the next morning and it started right up. 1/2 mile from home it starts to run rough and wants to die. It does this for a few minutes and then perks back up and runs fine for however long the trip is. It will always re fire and have no issues. Every morning it's the same game as described above. Within 1/2 from home it's doing this. Seems to be fuel delivery related, but why would it start after sitting overnight, and then after its little fit, run without an issue?

No codes in computer.

Golf IV / Jetta IV :: Brake Light Flashes 3 Times Then Stay On / GLI Will Go To Limp Mode

I have a 03 GLI 24V VR6 6 speed and im having an issue with the brake light.. ive checked all the fuses and emergency brake sensor and they are all good, the issue is the brake light flashes 3 times then will stay on almost immediately and whenever it does the entire drive of the car changes.. without the light on the car runs fine but when it comes on its like the car goes to a limp mode and is leaning out on fuel.. it wont rev past 4k it falls on its face and basically jerks along until I get where I am going.. I've replaced ABS speed sensors, MAF, and front brakes and axles recently.. before this was an random issue that would come and go but now its almost every time and it makes it undriveable..

Golf IV / Jetta IV :: When AC Is Switched On, Compressor Runs Without Going Off

In my 2001 2.0, my AC has been blowing hot air for a while now. It was intermittent at first but now is constant.

The compressor runs without going off when the AC is switched on. I can tell because I see the compressor clutch engaged and spinning.

I tested with AC manifold gauges and these are the readings I got.

Engine off : Low is 0, High is 135

Engine on, AC on full blast after running 10 min at 1500 RPM:

Low is 4, High is 135

Looks pretty bad.
