Car dumbie back again with another question.The diagnostic for my check engine light indicates numerous cold start misfire codes. The cylinders are OK. That was checked during the diagnostic.The fuel intake is carboned up. It is recommended that I clean the intake manifold. Does this mean cleaning the fuel injectors, the throttle body or both? 2006 Passat VW....
View 1 RepliesThe 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.
I have a 2006 passat and the check engine light came on so I performed a scan, the results are below. fault codes... which ones would need to be repaired immediately?

[Code] ....
Yesterday my car had a rough start (lasted all of 5 seconds) and it threw the check engine light on. Now other symptoms. It was a rough start, almost like a misfire then it idle fined, and drove my 60 mi commute home without issue. I had fine acceleration, gas mileage idle etc.
I got home and turned it off for 10 min and it then started normally and ran fine again. I'm thinking it was just a random miss that threw on the light, but I'll take it to Advance to get the code later today.
I replaced the plugs about a year ago with cheap-o plugs so it may be time for a replacement again. I thought maybe an o2 sensor but there wasn't a drop in mpg, at least anything noticeable.
And its been a few days since I've gotten gas so I'm doubting just a gas cap issue... The CEL did NOT flash, only solid the whole time.
So I have been having some troubles with my 2003 F150 4.6L ... Truck has been running rough and the check engine light was on so I decided to get the codes read and I got back P0302 and P0304, which from what I understand is a misfire on cylinders 3 & 4. At the same time I got Ford to do a little diagnostic and this is what they wrote for me:
"The connector for the number 2 coil is broken and will not stay plugged on to the coil and the number 2 coil is not working / replaced the wire for the coil still running rough removed the coil and plug. the plug was very badly fuel soaked started the vehicle to see if there was spark at the plug. OK. Suspect either a injector issue or a compression issue cleaned the plug seems better. "
So of course they quoted me for the works. They say I should replace the coils, plugs, and injectors??? I am pretty mechanically inclined and think I could change these things myself since I am on a budget. One tech told me is that the plugs can seize in these engines often and could scrap the whole thing??? Seems a little weird. If that happens though what could I do?
My check engine light came on the other day, with no symptoms or problems. Today I stopped at the Auto Parts store and had the codes read. They were P0440, P0441, P0446, and P0301. They are for the EVAP system and misfire.
I had read here that one of the codes could be for the gas cap so I tightened it and then, also as read on here, disconnected the negative 12 V battery cable to perhaps clear the check engine light. I was curious.
When I started the car again, I now have not only the check engine light, but the red triangle exclamation point. How would you proceed? The 12 volt battery is around 5 years old. The entire exhaust system was replaced last year.(not O2 sensors though)
The hybrid battery was replaced at 70,000 miles and I now have 110,000 miles on it. I really wonder why disconnecting the battery and reconnecting it caused more error lights to appear? Also, the Auto parts guy said his code reader was fine for my car but I seem to remember here that there may be a special Prius one.
This is my friend's car and I have never looked under a Subaru hood before. She is getting an intermittent check engine light with codes for cylinder misfires on one and three. Today, I inspected the plugs and all four looked identical, a nice uniform tan color and good condition. No sign of deposits or oil. Did a compression test and found the driver's side bank at 155/150 and the passenger side bank at 185/190. My question at this point is which side is cylinders 1 and 3? The front-most cylinder is on the passenger side. Is this the number 1 and 3? If so, then the low compression on the other bank cannot account for the misfire.
View 5 RepliesBought a 2006 (later production) with 25,000 miles over the weekend. Couldn't pass up the price and the warranty (1 year left + CPO). Picked up the car Saturday at noon..... had to drive to DC for business and the CEL came on when I turned on the car this morning. I researched at lunch that it could be a cold start misfire but I am already pretty heated about this. When I get home tonight I am going to plug it in to my OBDII scanner and see what I can pull. If it is something bad.... I am giving it back to the dealership.
View 24 RepliesRecently I bought an 01 Passat with a V6. Intermittently, when I go to start it, it cranks and cranks and doesn't catch. When this happens, the EPC and check engine light come on.
Other than that it is a fine car, I'm the second owner, and it was thoroughly maintained at VW dealerships and specialist. Recently there was a new oil pan and starter put in (w/in a month--previous owners).
We have a 2003 VW Passat 1.8, front wheel drive. The check engine light is on. The code is p0778. When we start the car the gears light display lights up in red for all gears . We put the car in reverse, back out the garage and when we stop, we get a bump. And we shift to drive the car moves slowly with some hesitation.
Sometimes after the car runs for 10 minutes, then turned of for a few second then started up again, the problem goes away. Before this problem started, we would start the car in the mornings, and put in "R" , and only the reverse gear would light up. (which is the way it is suppose to work).
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.
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.
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?
View 7 RepliesThe light just came on in my 06 Sonata 3.3L, showing many codes... P0171B, P0172B, P2187, P2188, P0174B, P0175B, P2189, and P2190. All of these just came on at once, within the last hour. Everything that is stated is regarding Too Lean or Too Rich on Bank's 1 & 2. Where to start on this...
View 9 RepliesMy check engine light popped up the other day and when ran, 3 codes popped up: p2414, p2195, and p0170. From what I could gather it looks to be the O2 sensor is bad. This would be the one on the exhaust manifold, correct?
Also, what would cause the o2 sensor to go bad in the first place? My 09' has roughly 65k miles.
Our second car is a 2007 Accent, 125KM's (70 miles). Today the engine light came on, I drove it very slowly to my indy mechanic and she is not throwing any codes. Engine temp was fine and she just had an oil change.
Engine light turned itself off so I drive it home and on the way it's all good then suddenly .... she dies. She starts again and I get home, i idle in the driveway and she stays on but a little rough as she is sitting at 800RPM, is this right or a little low?
Check engine light came on yesterday evening. Advance read the codes as P0100 and P0171. The guy said something that it may be related to the mass air flow sensor. The car seems to run fine.
View 2 RepliesOk so we have yet again the engine light on...we did a test and we have the codes P2004 and P0642. What can it be the problem this time??? what can cause this codes and is it expensive to fix? We just fix the care a couple of weeks ago( codes P0507 and P0171) and we are sooo tired of having problems.
View 4 RepliesI just bought a 2000 VW passat with 63k. I had it for a week and check engine light came on. 30 v engine ....
p0431 /16815 bank 1 below threshold??
p0421/16805 bank 2 below threshold??
Cat? or 02 sensors???
Bought a 07 GS450h w/ 82k on it last week thursday. car was serviced at 1 dealer it's entire life and battery was changed before I took delivery. After 100 miles of driving check engine light came on and i read 10 codes.
The codes are:
P0300 multi cylinder misfire (6 times)
P0301 cylinder 1 misfire (2 times)
P0303 cylinder 3 misfire (2 times)
Am I just looking at a simple spark plug change or is there something in particular I should look for? Is it worth the effort of bringing it to the dealer to repair?
Just bought 2007 Gs 350 in Dec 2015 with 60k miles. The other day I filled up with gas and drove to work. On the way home check engine light started blinking, check VSC appeared on display screen and traction light came on, car ran rough, and wouldn't accelerate. Got home and searched the net.. So I removed gas cap... No change.. Then removed neg battery cable for 10 min. Fixed problem for about 10 min. Then it all happened again. Next morning took it to Lexus dealer. The rep called and said it gave misfire cylinder 3. They said they checked valve springs and they are good, exchanged coil pack with different cylinder and still misfire #3. He said has to be injector so they want to replace injector ....
