2001 Hyundai Accent High RPMs - At About 100km/hr Revs At About 4000rpm
Three months ago I acquired a car from my brother. It was a 2001 hyundia accent gsi. The car had sat unused for 10 months and because of this I had to put some work into it. It has a new battery, new starter and new engine belts because one snapped upon start up the first times. I have also had the oil changed.
For some reason it is reving really high. At about 100km/hr it revs at about 4000rpm. I have talked to my brother and he said it did not do this before. It is changing gears because I can hear it and watch the rpm's drop before going back up. In 3rd gear at 60 km/hr it revs at about 2100 rpm's.
Golf IV R32 :: Misfiring On Cylinder 2 And 5
Happened a few times on me lately. While pulling towards the top of 5th, I'll start to see the check engine light briefly blink as if the car wasn't sure, then at the top of 5th, she'll start misfiring on cyl 2 and 5. It's only during the long haul pulls that this occurs. My plugs and coils were all changed about 1k miles ago.

The car already has a cel even though I just bought it. Drove home from work this morning had no problems, went to go shopping no problem, come out start my car and it won't idle right, problem. The Cel flashed at me and once driven a tiny bit stayed constant. Seems like a cylinder is misfiring because of the sound it makes and it is hesitant when you give it some gas. What could it be, coil packs (which is what is was in my 24v) MAF, spark plugs?

I am having a recurring problem, My engine keeps misfiring. I have replaced the spark plugs, ignition coils and pcv valve with all new parts and and fixed it for a little bit but now my car is misfiring again, and Im hoping its not the head so need to narrow down what the problem is...
View 1 RepliesGolf IV / Jetta IV :: Won't Start - Misfiring - CEL Came On?
So leading up to today ive had some bucking under load which felt like misfiring to me. I borrowed my friends VCDS cable, checked MAF, checked o2 sensors, checked cat. They are all good. This problem is constant but i did get a misfire code once (random, cyl 1, 2, and 3). I cleared the code and they never came back.
Today as im driving home from work, the bucking problem was much worse. Then the CEL came on. I just checked the code, and it was system too lean. I cleared the code and now the car will not start. It cranks, shows rpm on VCDS and sputters but doesnt even come close to starting.
Golf IV R32 :: Misfiring At Idle After Startup
Car has been running flawlessly up until about 3 days ago. One morning got in started up and started misfiring at idle. Didn't think much of it as it does that on cold start. Driving down the highway when I apply 5-10% light throttle the car bucks and doesn't feel smooth. WOT is fine. Pulled into a gas station to fill up and it stalled as soon as I put it in neutral. When I tried to start it back up it started for a second then stalled out again. Finally I gave it some gas while I started it up and got it to idle on its own (idled around 600 rpm, down from my usual 800 rpm).
At this point I am thinking boost/vacuum leak. I leave the gas station and get caught in traffic. Car is not overheating. All of the sudden I notice a bunch of white smoke coming from the tail pipes. I pull over pop the hood to check coolant. No leaks and bottle is full. The white smoke smells like burnt oil. finally notice a VERY small oil leak at my turbo oil feed line. I checked the oil level and it was still exactly where it needs to be.
I have my buddy at the dealership looking over it now but I am really worried that I might have blew the turbo..
Golf/GTI VI :: Coil 1 And 3 Misfiring Continuously?
My car misfired multiple times in two days i replaced coil 1 & 3 & it misfired again i took the coil that i replaced and put it back and the car was fine so. i don't think its the coils and i changed spark plug in coil 1, didn't work so I doubt it's coils.....

Misfire cylinder 1 and random misfiring

Changed the plugs, wires, and coil pack Used and old timing light and getting spark in all wires so can't be the coil pack
Fuel injector, O2 sensor, any other things?
Golf IV / Jetta IV :: CEL Flashing Saying Cylinder One Is Misfiring
I have a 2001 golf with a 2.0 AVH engine. I recently replaced the coil-pack and was very pleased that the engine was running better, the only problem was the mpg was still kinda low in the 24-5 range when it used to be 29.
I tried to do a compression test but I didn't prepare properly, I thought you left the coil pack plugged in and the fuel fuse. Now I have a CEL that *was* flashing saying cylinder one is misfiring though it has stopped flashing. I drove it 13 miles home and it did improve but its still running rough. Very reminiscent of when my bad coil pack was still in there, a real lack of power.
So I have to ask, what can I do from here? Have I damaged my coil pack or cylinders? Will this likely go away on its own? Is there anything I should do?
Golf/GTI VI :: Cylinders Misfiring Lost Acceleration
So last night i was driving and i made a turn onto the highway and speed up to pass this slow ass car :thumb down: and as i did i lost acceleration and my car started to rumble like when you use a high gear when u make a turn while moving that slow acceleration. And as that happened my engine light turned on and my EPC so i drove it well barely made it home. i had a friend with his VAGCOM come to see whats wrong it said cylinder 1&3 are miss firing so he took his ignition coils out of his car swapped them in my car and we drove it around and it drove fine and no fault codes. so now my issue since i have GIAC, CAI and APR full exhaust if my warranty will cover to have them put new ignition coils since i did get an extended warranty. I'm just afraid they won't.
View 7 RepliesGolf IV / Jetta IV :: 1.8T - Misfiring Cylinders With EPC Light
Is it possible that disconnecting battery causes a misaligned throttle body, which in turn causes the EPC light to come on? And does a misaligned throttle body also cause misfiring cylinders (1 & 2 in this case)?
View 3 RepliesGolf/GTI VI :: Misfiring - Code P0300 And P0302
I have a 2011 GTI (purchased new in 2010) with a stage 1 APR tune and a carbonio stage 1 intake. 71K miles on the car, tune has been on it from nearly the beginning, no issues. I have religiously filled with 93 octane gas -- like, always. The other day I was filling up an empty tank in NJ -- land of mandatory attendants -- and I accidentally said "premium" instead of "super." (I normally self-serve in PA). Before I realized what had happened, I had a full tank of 91 in the car.
I run the 93 octane program on my APR, and I couldn't remember how to switch, so I've been running around the last few days that way, seemingly with no issues. I'm not even sure what's supposed to happen if you burn 91 while in the 93 program.
Anyway, yesterday I happened to go full-throttle in 1st or 2nd gear, and I ran into a little stumble. Strange, but I figured maybe this was the result of my refueling mistake. So, I got out my APR manual and figured out how to switch programs down to the 91 program, which I then did. Took the car out again, and was still able to get it to stumble, eventually with a blinking, then solid CEL. A quick VCDS check showed a "Random/Multiple Cylinder Misfire Detected" -- P0300 and "Cylinder 2 Misfire Detected - MIL" -- P0302.
Now at 71K miles, I've never replaced the coils or the plugs, although I have had 2 intake manifolds replaced under warranty. I'm kind of figuring the octane and tune are not really causing this and it's probably just in need of some coils/plugs. what is "supposed" to happen if you run 91 octane on the 93 program? I haven't tired backing down to stock yet, but I could certainly do that and see what happens.
Golf IV / Jetta IV :: 2000 VW VR6 Misfiring In Cylinder 1
I recently bought a 2000 jetta vr6 MK4 and since i have had it its had a misfire problem. So its saying that its misfiring in "cylinder 1" and sometimes when I clear the code it will stay off for the whole day. I did everything I could think of. I replaced all the spark plugs. I replaces the plug wires. Then i bought I new coilpack. and its still misfiring.

CEL came on and the report says #2 cylinder misfiring. Changed plugs, wires and coil. Last step was to change the #2 fuel injector. I changed the 2nd injector from the left but I'm still getting the same message. I was wondering if maybe they aren't numbered that way. It's a 2004 Jetta with Car engine: 2.0L L4 SOHC 8V. Did I change the wrong injector?
View 1 RepliesGolf IV / Jetta IV :: Misfiring After Engine Is Hot But Only Under Certain Load
I'm getting misfiring after the engine is hot, but it only shows up under certain load. For example, if I'm in 3rd gear at about 2500 rpm and I give it some amount of throttle, it wont misfire at all but if I give it just a hair more (maybe past 50% or so), it will start misfiring badly and the blinking CEL comes on. The codes it's triggering are misfire on cyl 1 and multiple misfire.
I replaced the coilpack about 6 months ago, that's why I'm hoping for some feedback before I drop a few hundred dollars on another one. I had the plugs out very recently and they look fine. The shape of the wires are difficult to get multimeter probes on so I haven't checked them.
Golf VI R :: Misfiring With P1545 Throttle Body Code
Started my car this morning to warm it up, idled for ~ 20min. weather conditions. I returned to my car, and it was misfiring and threw the p1545 throttle body code. There was a mk5 tsb for a similar problem involving wiring. 49k miles, stock tune, w CTS catted dp.
View 8 RepliesGolf IV / Jetta IV :: 2004 - All 4 Cylinders Misfiring Randomly
So I have a 2004 jetta GLI (1.8T) with forge splitter valve and short ram intake. I went and got my codes pulled and all 4 cylinders misfiring and random misfires. I replaced both coil packs and spark plugs. check engine light popped up again after about 20 miles and same thing. I just bought the car so I'm not sure how long it has been running with these misfires. I just got the timing belt replaced. I know it could be off a tooth. (Wouldn't a code pop up though for it?) How could I check that. And I also took my MAF sensor off as well and no change. Heard it could be clogged cat, any way to check? I've also cleaned the throttle body. It runs fine when I'm driving, just a rough idle.
View 15 RepliesGolf IV / Jetta IV :: Major Temporary Misfiring When Warming Up
2002 Jetta 1.8t, auto tranny, 90K miles. Recently took it in and had all coilpacks replaced under VW's recall.
Sometimes when it's been sitting out in cool air for a long time (in Texas summers, this is nights-only), about 3 miles in it suddenly starts misfiring- BAD. Check Engine light comes on. Lasts about 30 sec, then goes away and doesn't come back for the rest of the drive. WTF?? I can't make it happen on queue.
I heard about the all-too-common grounding problem on the engine harness. I did find a significant resistance between the ring terminal on the head and the battery (-). I tied the 3 ground posts under the battery together with 12ga wire and crimped terminals, and ran another 12 ga wire up to the engine block ground right under the ring terminal that grounds the coils, which should have shorted past any weak spot on the harness. PROBLEM STILL OCCURS!
Scans showed:
17766 Cylinder 2 Ignition Circuit: Open Circuit
16682 Cylinder 2 Misfire Detected
16684 Random/Multiple Cylinder Misfire Detected
17658 Low Fuel light (only ~3 miles after lighting the Low Fuel warning, I don't think the fuel pump's running dry just yet here)
Seems to focus on Coil 2. But last time I did this I got these errors for Coil 3 and swapped it for a new replacement I had in the trunk in case one went out unexpected. Well now it just says Cylinder 2. Just did it again tonight after clearing codes and got these same Cylinder 2 errors again.
Actually I started to wonder... I've been running the tank close to the "low fuel" light to check my actual mpg usage (no display for it in my MK IV), but fill back up a few miles after it lights. I can think of a couple of spots on the late-night drive back that I see this, one's after a hill which might cause a fuel pump to run dry temporarily, but another's a light downhill then up a light offramp. I don't think the tank's been low every time this happened but I'm not sure. Well, a couple of times it's been mostly level in the parking lot anyhow and misfired a bit right off the bat when starting, so probably not.
Wouldn't there be some sort of "low fuel pressure" code if fuel starvation was actually the issue going on? Hmm, I went looking and I'm not sure there is one for a MkIV, there's errors for fuel trim but I don't think you get those in short-term. This is kinda scary how it just goes out while driving, and I can't do much to reproduce it or test out fixes.
So looking further, other people report what may be intermittent fuel pump issues when the tank goes low. But could that result in "Cylinder 2 Ignition Circuit: Open Circuit"? I mean the coils will still electrically read as firing. Of course if the system gets all glitch-y, the software may be making a mistake somewhere and report this wrongly.
Golf VI R :: Consistent Misfiring - EPC And Traction Fault Lights?
Started my car up the other day after sitting overnight at temps around or below 0. Started as I would expect in the cold and I walked away to let it warm up. After about 10 minutes I went back to find the car misfiring very consistently, sounded and felt like one whole cylinder was dead. When I attempted to rev the engine it would not rise above 2k RPM and continued misfiring. I shut the engine off and restarted, this fixed the misfiring however the EPC light and Traction Control light remained. The tire pressure light was also on but this is to be expected due to temps. Also there was an "!" instead of my odometer reading, I am guessing this is because I had previously been using cruise control when I turned the car off the night before. Anyways, after a quick drive all lights went away including low tire pressure but seen issues like this from cold weather??
