Golf IV / Jetta IV :: 2000 - Cylinder 2 Misfire And Engine Sputter
2000 GTI GLS 2.0L ... I understand I need to replace the Ignition Coil Pack on my car. I have looked on ECS Tuning to find the coil pack, but from all the pictures I see of other people coil packs they look nothing like what mine do. So I'm wondering if they are different for my specific car? So the issue that I have is my engine sputters sometimes, but more so when is wet outside. Its only cylinder 2 misfiring currently, and I replaced my Fuel Filter and Fuel Pump already in the past 4 or 5 months. Also a local shop had done some work recently and I know they had replaced the spark plugs. So I'm just wondering what coil packs I need for my car, and how I would go about replacing them. From what I saw online with other 2.0L (They weren't GTIs tho) was that the coild pack was behind the SIA pump or something like that, and they are a small black box. It looks to me that my coil packs are inline above the spark plugs and cylinders?

So recently I took my engine apart to do a valve cover gasket and Ecs tuning 2.0 coil conversion. I noticed a good amount of oil in the plug tubes so I got out my trusty soap dispenser and started pumping out oil. Pulled plugs and cleaned them (wanted to make sure oil was all out b4 getting new) also while I had it apart I wanted to take intake off, ( just to polish it and clean out any carbon inside).. Well I never ended up doing that. I removed the injector connections and realized it was to much work for such little satisfaction. So I plugged the injectors back in.
I got my car all back together and now I'm throwing 6 cel codes!! P0102 (maf) which I'm assuming b.c I took it off for so long, p0201, p0202 ( injector 1 and 2 miss), then some misfire codes p0300 (random) p0301 (cylinder 1) and p0304 (cylinder 4). The car starts runs very rough then cel comes on and blinks. I was thinking maybe the oil getting down to the combustion chamber couldn't be the best for it but it would just burn off. Only other thing I did was take off the thottle body and cleaned it.
Golf IV / Jetta IV :: 2001 GLS 1.8T - Cylinder 1 Misfire / O2 Sensor Codes
I bought a 2001 golf gls 1.8T (AWW) about a month ago and it was running pretty bad, was throwing some codes, cylinder 1 misfire and some o2 sensor codes, I replaced the coil packs and spark plugs and then cleaned the MAF. It was still running bad ,rough idle and power loss. I figured it had to be some kind of vacuum leak, I replaced the PCV valve, cleaned the intercooler and put on a silicon TIP. Still had some rough idle and power loss, checked for vacuum leaks, using the good ole starter fluid method and found my intake manifold was leaking so I replaced that gasket. STILL rough idle and power loss, now I'm pulling codes for o2 sensor and a misfire in cylinder 3. My question is, should I replace my pre-cat o2 sensor or replace my MAF sensor? Or are there other things that should also be checked/replace.

So my girlfriends's 2001 2.0 Golf (engine code AVH, 153k miles) began throwing codes for misfire on cylinder 4 and for the o2 sensor (post-cat) recently. I went ahead and replaced the spark plugs, wireset, and the coil pack. They were way overdue. The CEL went away for like 30 miles, and then came back. Now it's reading misfire on cylinder 3 and the same thing for the o2 sensor. What else it could be? Search is coming up blank, most people replaced the coil pack and the CEL went away.

I get some bucking under load between 1500 and 3000 rpm. This issue is more noticeable when the engine is warm. When it does this it makes a sound that to me sounds like a misfire from the exhaust, but I've never gotten a misfire code.
Sometimes i get codes p0411 and p0420 (secondary air injection and cat efficiency) but VCDS tests say my cat and o2 sensors are all good.
Golf IV / Jetta IV :: Check Engine Light Blinking And Sputtering On Idle - Misfire?
On my way to work, my check engine light started blinking and car was sputtering (real bad on idle). I ran the code and it came back with misfires codes. I changed the coils/plugs, fuel filter and fuel pump last year. Can the coils be bad already? When I clear the codes the car will run fine for a little while. But after a couple miles CEL will blink and the car will run roughly again.
Car : 2004 Golf 2.0
Codes:
16684: random multiple misfires
16648: fuel injector #2 short to ground
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.
View 4 RepliesGolf IV / Jetta IV :: Check Engine Light With Error Codes 17748, P1340
I'm having some problems with my 05 1.8T GTI. I've had a check engine light for about 3 months and finally got a diagnostic tool (VAG V-checker). Right now I have one code 17748.P1340 Camshaft position sensor-G40/engine speed sensor -G28: incorrect allocation.
I researched a little bit and talked with some of the guys at the local VW dealership. From what I learned this could be related to (obviously) faulty camshaft position sensor and/or faulty engine speed sensor. So I've replaced both of these sensors and even cleaned the Mass Airflow sensor.
I cleared the code and after driving about 5 minutes the code came back. Also I recently had a P0300 and P0304 cylinder 4 misfire default code. So I've changed all of the ignition coils too since I heard they were recalled a while back.
Golf IV / Jetta IV :: Running Rough And 3 Codes Stored - Cylinders 2 And 3 Misfire
So my daughter's 2000 Golf Mk4 with 160,000 miles on it was running rough and had 3 codes stored - cylinders 2 & 3 misfire and a 411 secondary air injection problem.
Having had the misfire code before I swapped injectors around and the error code moved cylinders with the injectors so I attempted cleaning them and also cleaned the throttle body and intake manifold. At this point car still running rough but also started smoking badly.
Replaced the following items:
- Spark plugs
- Spark plug wires
- PCV valve
- PCV hose
- Fuel injectors w/ remanufactured
Hose reconnected between secondary air injection pump and air intake - previous owner had duct-taped it in when he couldn't get it to seal I guess. I've never heard it run.
Car running better, idles more smoothly, doesn't stumble or stall like it did before, no error codes coming up BUT car smokes a lot and the fumes make me feel sick just driving it a mile.
The car had never smoked like this before, hasn't had a whole lot of love the last year or two but no real problems either so why the sudden smoke?
At first I assumed it was cleaner being burned off but that should have been gone in under a minute and this is on-going. It's bad enough to not only be embarrassing but apparently dangerous as the fumes are bad.
Golf IV / Jetta IV :: 2001 1.8t Stopped Running - Check Engine Light Blinking Because Of Misfire
So last Thursday I started my car up in the blistering cold and it ran fine for about a minute and started to misfire so I shut it off. It hasn't ran since. When that happened the check engine light was blinking because of the misfire. I didn't have a code reader at the time to read it. now that I got a code reader the damn thing isn't throwing any codes. it spits and sputters sometimes. I've had no previous problems with the car. Thinking It might be a weak fuel pump or bad coils and in not sure how to test them.

Golf IV / Jetta IV :: Codes For Random Misfire And Small EVAP Leak Detected
Okay, so a few weeks ago, my tire blew out on the freeway. Of course my spare wasn't in there and when I got one I couldn't get the lugs loosened. My 4way was too big on all sides. It was late, I am a single mother of two young kids so I had no choice but to drive slowly to get it off the freeway. The next morning I came back fully prepared, got my car in to get a new tire. I have been driving with ONE code for my CEL, but at the shop (where I use to work) I used the scanner and it threw 5 codes.
P0300 Random misfire
P0442 Small EVAP leak detected (this one was already there)
P0420 Catalyst system below threshold bank 1
P0301 Misfire cyl 1
P0303 Misfire cyl 3
My beautiful love is an 02 Jetta 2.0 4 Cyl. Now, since 4 of these codes popped up AFTER my first blowout (I turn 30 next month, knock on wood)
Did driving my car at 5 mph about a mile and a half (everywhere up until the gas station was NO PARKING) do something to my car? All of a sudden, any in town driving ESP IDLING makes my check engine light blink and my car has no power I just have to pull over wherever I am. I checked the car out myself on the side of the road and my cat was glowing. After this I do not drive my car.
So, what should I do. I did a tune up. Should I replace the 02 sensors then the cat?
Golf IV / Jetta IV :: 2000 GLS VR6 12v Codes Won't Go Away
Okay I have a 2000 Jetta GLS VR6. I had the engine replaced after i found out the block was cracked when replacing the heater core. ever since it was replaced the car runs great but it keeps throwing these 4 codes.
p1424 secondary air injection system bank 1 leak detected -intermittent
p0411 secondary air injection system incorrect flow detected
p1603 internal control module failed self test -intermittent
p0134 02 sensor bank 1 sensor no1 no activity -intermittent
The thing that is bugging me is that the sai pump is still running. On cold start it literally sounds like a Dyson vacuum. What i should try.
Golf IV / Jetta IV :: 2000 - Got Transmission Codes?
i have a 2000 jetta 2.0 i am in desperate need of a new transmission. Ever since I bought the car I rarely had third gear and today on my way from southeastern PA to northwest Ohio seem to pretty much completely lost first unless I really slam it in and fifth likes to disengage every now and then unless I hold the shifter in place both first and fifth were slowly giving me problems until it got really bad after todays 8 hour drive. My transmission code is EBP, is there any other codes I can put in my car from another 2.0 or do I have to get another EBP?
View 2 RepliesGolf IV / Jetta IV :: 2000 VR6 Random Misfire In Cylinder 2 And 5
About a month ago my wife's 2000 Jetta with the VR6 engine in it started acting up and throwing codes. The codes it threw were for random misfire, misfire in cylinder 2, and misfire in cylinder 5. Starting out, we changed spark plugs, fuel filter, and made sure the injectors were clean.
The problem didn't go away so we water tested the coil and wires, but they passed that test. The wires were quite old and out of spec, while the coil was in-spec across all terminals, according to the vehicle service manual, so we installed some new OEM leads this weekend. While installing the leads we noticed a disconnected vacuum line and reconnected that as well.
The vehicle was driving great for two and a half days, then today while I was sitting at a stop light, it started missing really badly and felt like it was going to kill. It did this for about 5 seconds, then recovered and ran smooth for about 5 seconds, before getting really rough until I started driving when the light changed. It didn't do it when I drove it a few hours later at all. This episode didn't throw any codes either.
What could be causing this issue? Would the MAF cause the intermittent missing, or is it possible that the computer is going bad?
Honda - Cr-v :: 2001 - Engine Light Remaining On With Misfire Codes
My 2001 Honda CR-V with 120,000 miles has been sending misfire codes for the past couple of weeks. I replaced the distributor rotor and cap, plugs (NGK's) and wires, and the light disappeared after a couple of driving cycles. Then, it came back on about a week later. I had it diagnosed at a shop for compression and everything was good. I had read about the valve issues so I had the valves adjusted.
The car seems to run without any hiccup at all, and its been over 150 miles since the valve adjustment but the engine light remains on with the misfire codes.
Golf IV / Jetta IV :: 2000 - CEL On / OBD Scanner Won't Read Codes
The past week, the CEL of my Jetta 2000 was on, and a couple of days after, was off. But yesterday was relit. I take my car to Auto Zone to check codes with scanner, but was impossible read any code, the lector can't connect with computer. I thought in fuses, but the fuses are fine.
Searching on google, i found that the reason could be the aftermarket radio, but I am not sure about that, the connections are seen aparently fine. I Read in one thread that disconnecting the aftermarket radio harness is enough to can read codes from computer.
I read also that the scanner could be incompatible with VW cars, but I don't think that, because AutoZone should have a scanner compatible with most of the common cars models.
The fact is that I don't want to get in troubles with the harness of radio, I don't have tools like multimeter neither knowledge about electrical systems, i just want to know if disconnecting the radio harness is enough in order to read codes. (in case of the problem be on the K-line wire).
Golf IV / Jetta IV :: 2000 - Blinking CEL / Misfire / Oil On Spark Plug
2000 Jetta AEG ... An intermittent CEL light turned into a blinking CEL after a few months. Checked codes and it threw a P0303 (misfire on Cyl 3).
Pulled the plugs and found this:
There was oil dripping off of the plug from Cyl 3.
I last changed the plugs in July 2014 and only drove around 10k miles this past year.
When I changed them back then though Cly 3 looked like this:
Before I changed them back then I had an oil cooler gasket fail on the freeway and oil shot everywhere under my hood. Obviously oil is in there and it is causing problems.
I have read online and most of what I have read says that it's likely an issue with the VCG (Valve Cover Gasket) or the PCV (Pressure Control Valve) that is allowing oil to get to that part of the spark plug tube. I've also seen some non VW stuff talking about replacing the spark plug tubes.
Also it does appear that there is a little bit of oil around the threads of the other plugs but nothing getting to the all the way to the tip around the electrode.
I have pulled the plugs, wires and the ignition coil as well ... I'm ready for whatever. I am by no means a mechanic but I am capable of following instructions and doing what is needed. My problem is generally finding out what is needed to be fixed.
Passat (B5) :: 1999 - Check Engine Light On With DTC Codes / Misfire After Startup
The check engine light on my 1999 1.8T Passat is on. It started with a little miss right after startup. Then in neutral, after revving the engine to say 1,500 rpm and letting off the gas, it would nearly stall. I plugged in an OBDII analyzer and came up with codes P0102 MAF or VAF circuit low input and P0304, Cylinder #2 misfire. I replaced the spark plugs, as they were old anyway. Still the same symptoms. Then I replaced the mass air flow sensor.
The check engine light still went on after it was cleared, except this time it was P0302, Cylinder #2 misfire, P0102, P1613, Auxiliary inputs aux. outputs control, and P1426 Mfg. Control/auxiliary emission controls. Soon after, the car started running fine on it's own and I again cleared the codes.
Then a day later, the check engine light is on. This time, it is only the P1426 - Manufacturer control auxiliary emission controls. The Bentley manual calls it Tank Vent. Valve Open, which doesn't mean anything to me and the Bentley manual is of no luck. (The error code almost implies that it is the famous loose gas cap, but I have checked that - unless the gasket is bad). FYI: I have 99K miles on the car.
