Caravan/Voyager :: Check Engine Light Came On And Started Blinking - Random Misfire
I have a 96 Grand Voyager that had had sat for a year undriven or started due to being out of state. It ran like a champ when I parked it. Now I charged the battery and went for a drive on the freeway and my check engine light came on and started blinking. I had the code read it came back with 2 codes a P0306 and a P0300. I noticed that the cylinder 6 spark plug wire was arcing on the core support. So I replaced all the plug wires and spark plugs with Champion platinum spark plugs. I cleared the codes and took it on a test drive and the P0300 code came back. Is there anyway the old gas is causing the random misfire? or what else could it be?
View 1 RepliesDodge - Neon :: 1997 - Check Engine Light Has Been On And Causing Random Misfire
I have a 1997 Dodge Neon with about 153,XXX miles on it. My check engine light has been on and i know that is caused by a random misfire. But more recently i went to start my car and it started but ran for less then 10 seconds and died. I tried to start it again and it wanted to but wouldnt make the final step i guess. We checked my spark plugs and i had oil sitting in 3 of the 4 there are. We have tried starting it again after cleaning the oil out and it started on the first try, I am just afraid of messing anything else up so until we figure out why it did this to begin with the vehicle is off limits. My Fiance said we need to replace the spark plugs and a gasket.

View 1 RepliesSonata NF (2006-10) :: Random Misfire Code P0300 - Check Engine Light Flashing
I know it is a random cylinder misfire code however I started my car in the morning and it was fine I moved it and put it back in my driveway. I started it up later and waited for it to heat up i came back outside 10 min later and my check engine light was flashing and my car was shaking like crazy you could tell the engine was misfiring like crazy. I had under a quarter of a tank but not empty yet. I shut it off and turned it back on and it was still doing it. I drove the mile to the gas station the way it was.
Under partial throttle it was revving to 4500 and over 5, had to let of throttle to make the car shift up a gear. I filled up and started the car again performed fine after that however the check engine light was solid now and still on. I went to my local mechanic and he read that code P0300. I changed my spark plugs that day and they were crap the original spark plugs I have 65,xxx on my car now. Car is smooth now. I cleared check engine when i saw him first and it did not come back on all day even before i changed the spark plugs later that night. Why my light was flashing and why my car was acting like that till i filled up?
Elantra XD (2001-06) :: Check Engine Light Will Pop On Occasionally And Code Reads Random Misfire
2004 Elantra AT ... 6 months ago top of the radiator cracked caused it to overheat and blow the head gasket and warp the head. Repaired that and compression is fine now. It ran great for 4 months but now it randomly stalls. at or near idle. Seems to do it more at operating temp rather then cold. Occasionally the check engine light will pop on and the code reads (random misfire). It acts just like it has been shut off. But immediately restarts.

View 2 RepliesToyota - Corolla :: 1999 - Check Engine Light Came On Flashing / Cylinder 3 Misfire
I have a 1999 Toyota Corolla. 4 cylinders.
I was on the road about 2 hours from home when my check engine light came on flashing. It stopped flashing so I kept driving. Three more hours of driving at highway speeds and it only came back on once. I then took it into autozone and the code reader told me I had a Cylinder 3 Misfire. The guy told me to change my spark plugs and I would be fine. It was time for a spark plug change anyhow so I drove home and did it. After I changed the spark plugs the car did not start at all. It would cough and sputter and try to start but not actually start. Changed the spark plug wires and then the car stopped even coughing and sputtering. It just didn't start.
I then noticed that my fuel line that feeds directly into the engine was rotten right next to the engine and if I pushed it in I could get the car to try to start. (Try and fail, but at least try.) The fuel line is a molded piece of rubber that flares at each end. It was one of the flares that was rotten and didn't seem to be sealing anymore. The hose is 7 mm inner diameter in the middle and about half an inch on the ends. I took some 3/8 in fuel line and used it to cover over one of the flares. The car tries to start now but wont. 3 of the four cylinders crank. I don't understand how I could break my car on such a simple repair job.
Nissan - Maxima :: 1998 - Service Engine Soon Light On / Random Misfire?
I have a 1998 Maxima with 57K miles on it. I just bought it about a month ago. Anyway, a week ago I noticed It felt very "choppy" when I shifted into Drive or Reverse. It felt like it was going to stall but it never did. The Service Engine Soon light has been on for about 3 weeks but now, when I go up hills especially, that light blinks. I can still drive it but I shift into Neutral at stoplights to avoid hearing the rough idle while in Drive. Went to Pep Boys yesterday - they had the car for about an hour and then informed me that they would need to keep the car for a full day because of the "complex issues involved" - especially concerning the codes. The codes they read were:
p0300 random misfire
p0325 knock sensor
p0440 evap emission
My car passed smog test abut 3 months ago. I can drive it OK it just is very choppy and so there's not a lot of power, especially going up hills.

View 13 RepliesSaturn - Vue :: On Random Startups Power Reduced And Check Engine Light On
I have been battling a random reduced power issue with my 2004 Vue, 85000 miles, 4 cyl engine with manual transmission. On random start ups I will get the reduced power and check engine lights. No codes are logged but the freeze data will read mostly 2176 and occasionally a 2101. I have replaced the throttle body and pedal assembly plus checked and reseated the ecm connections. The problem still shows up randomly at start-ups. If it does appear, it seems that if I shut the engine off, turn the key to on without the engine running for about a minute, then restart the car, the car will start ok. It's almost as if the ecm has to relearn the throttle or pedal positions when this occurs.
View 4 RepliesMazda - Millenia :: 2002 - Check Engine Light On / Multiple Engine Misfire
The problem that causes the check engine light to come on cannot be traced. The diagnosis is multi engine misfire. The dealer has checked and recheckedbut problem still exists. The last time my mechanic changed spark plugs he noticed oil on one of the plugs he removed in the rear side of the engine. He replaced the plug with the rest of them. Could it be that one or more of the spark plugs are sucking oil and causes the misfire? If so what could be the cause of that. Do I need a full tuneup? My dealer recommends replacing the cam shaft pulley because it's loose and this may or may not solve the problem. I'm not a mechanic but it appears as if the problem has something to do with the spark plugs sucking oil since the check engine light might go ou for a week or so and then come back on for a while. Lastly is it dangerous to keep driving the car especially on long trips?
View 1 RepliesCorolla / Matrix 2009-13 :: 2011 - Clunking At Random And Whole Car Jerks
I am having issues with my 2011 Matrix S. It started off bucking slightly when shifting. As time went on it started clunking at random. When it clunks, the whole car jerks violently then will start driving again. One time it clunked (if I wasn't wearing a seatbelt I would have been in the dash) I lost all power to my wheels while my car was revving at around 3000rpm, it did a large jerk/clunk and then I had power to my wheels again. Lately they have been just large clunks without losing wheel power. My car always seems to revv abnormally now and sometimes when trying to accelerate, I can have me petal to the floor and zero acelleration.
I've been in frequent contact with a Toyota dealer and they are great. I can't randomly recreate the episodes so it's hard for them to be able to diagnose the issue. I'm going to make an appointment for them to do a computer read to see if any codes have been thrown.
Passat (B5) :: V6 Check Engine Light - Misfire In Cylinder 4
I'll try to break this down as best I can. I went to my mechanic this am with a check engine light. My suspicion is 02 sensors. This was confirmed as a problem area, but separate they said I had a spuratic misfire in cylinder 4. With that info, i pulled the plug to inspect (I had just installed new ngks in it and they have 18,000K on em.
I put beldon wires on about 8k ago.) plug looked to be normal, but there was definitely a puddle of oil from the valve cover leaking. Oil went into the cylinder head but I didn't really think that was an issue. Nothing abnormal jumped out at me so I reinstalled plug and checked all wire connections at both ends and called it a day.
Then I drove it. Check engine light flashing. Major performance stutters, etc. I drove it for about 20 miles and hoped it was just the oil raising hell in there and it would burn off eventually. It hasn't gone away yet. Maybe coil pack. Can the single portions of that pack be replaced, all i see them sell is the full three as a unit.
Passat (B5) :: Check Engine Light On - Detected Misfire
I just received a check engine light and the diagnostics from dealer were that a misfire was detected for cylinder 1 , 2 , 3 and 6 .
What needs to be changed? and mechanic said maybe the complete coil pack and wiring . Although, the code was reset and i haven't had the CEL come on prob in a week now , so i guess no other misfire has happened.
Golf/GTI VI :: Check Engine Light Has Been On - Car Sputter And Misfire
So, my check engine light has been on for months. I knew that I needed a new oxygen sensor (block 1-pre-cat), so I replaced it today after the car began to sputter and misfire. Well, I thought that would fix the problem, but it hasn't. Some of the hesitation is gone, but the sputtering is still very bad. I'm going to replace the spark plugs tomorrow and see if that works. I was also told to clean out the catalytic converter, but I don't know how to take it off. It wouldn't hurt to just bang out all the debris. Any DIY on taking off a catalytic converter for a 2000 VW Golf GTI 1.8T?
View 7 RepliesChevrolet - S-10 :: Check Engine Light Come On / 4th Cylinder Misfire
2000 Chevy S10 pickup
Had the check engine light come on, and when I checked on the code it gave a 4th cylinder misfire. Autozone instructed me to simply replace my spark plug with a new oem plug.
I replaced the spark plug as instructed. After about an hour of driving, the check engine light goes off and I think, great! Problem solved. However, another hour of driving and the check engine light is back on again, without going away.
I headed back to autozone to get a readout, just to find that it's the same code. So I put another spark plug in. Same result - check engine light goes off after an hour, only to come back on again permanently after another hour.
Now, normally I would think, this must be the spark plug line that needs replacement,however I am sure there must be some clue in the fact that the check engine light turned off for an hour.
By the way, not sure if relevant, but I also found a lot of build up around the spark plug before I initially changed it.In fact, there was so much that I had to scrape around the plug with an awl, and blow out the crud with a compressor,just to get my socket into place without there being crud in the way.
Any clue what that check engine off/on clue might be?
Passat (B6) :: Check Engine Light - Cylinder 4 Misfire
Got the flashing check engine light and loss of power for few seconds and then the light stayed still, from time to time it blinks for few secs, usually when I push the gas pedal little bit more but it stays still, flashed only twice in 2 days for seconds. I connected computer (not VAG) and it says "Cylinder 4 misfire". I have app scheduled with my mechanic this Thursday, but still need to commute to work. Is it safe to drive?
