Passat (B5) :: 2002 2.8 V6 - Random Multiple Misfires?
I know the ignition coil are a big thing but I'm going to be buying this car this week and so I need to see how much less to offer the guy because of this issue. Is there anything other then the ignition coil that it could be? What's worst case scenario? And also would it be ok to drive it home about 60 or so miles with this going on? I'm guessing it's doing the misfires at idle.

So I took a trip from Dallas to Florida, and on the way back my check engine light came on. The car shakes at idle, almost like it wants to take off. I drove it back to Dallas like that since the car runs normal on the high way. I got it scanned at autozone and the code said it had multiple random misfires. I'll be taking to the dealer in the morning, but what it could be? The car jumped over 50K during the trip hopefully the dealer will be nice and cover it.

I have a 2001 1.8T Passat. I bought it used recently and have had tons of problems. I have been getting a lean air code for some time now and I think I recently resolved that. I had to replace a few vacuum lines, MAF, exhaust flex pipe (it was broken), fuel filter and fuel pressure regulator. The car was still running bad and throwing a lean air code (Bank 1) so I finally changed the O2 sensor and I think that did the trick. Now every time I start the car I get misfires until is warms up. I get misfires on all cylinders along with the multiple misfire code.

Getting multiple CEL's for the catalytic converters and cylinder misfires. Looking for threads that address these particular codes ie. 0431, 0421, 0300. 0303, 0306. I have a feeling that these are being caused from a vacuum leak and/or needing a reflash for the ECU.

View 7 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 RepliesMercedes-benz - C-class :: 2003 - Multiple Cylinder Misfires And Poor Gas Mileage
I have a 2003 Mercedes c230 with low mileage 70000. This was its first season not garaged. About 2wks ago when very cold started abruptly to misfire badly at idle with poor gas mileage and modest loss of power. I got codes on OBD II for multiple cylinder misfires p0301-4 (all 4 cylinders). No other codes. Also the MAF and O2 sensors seems to be giving normal readings, and I cleaned the MAF sensor (didn't take off. cleaned through screen connected to air filter housing). 1 or 2 of the spark plugs seemed fouled as had black oily fuel on them and the O2 sensor voltage readings were consistently close to 0.9v (high meaning reading rich air/fuel right?). Changed all 4 plugs and swapped around ignition coils. Seems a little better but still misfire. O2 sensor voltage reads now consistently around 0.7v and the new plugs are dry but already blackened (indicating rich air/fuel I think).

I replaced the Coil Pack & all spark plugs with genuine jeep parts from the dealer. What might be wrong or other things to check?
Camry :: 2011 L4 - Check Engine Light On After Trying To Start Car Multiple Times Without Gas
I have a 2011 I4 camry. I recently ran out of gas and decided to keep trying to see maybe if the car would turn on. After all that i gave up cranking the car on and decided to push to a gas station. After putting in gas (93 octane) I realized i have my check engine light on and another light which depicts a car with 2 swiggly lines.What that light means but its to the right of of lcd display which shows your mileage. I am taking the car tomorrow to the dealership but I was wondering is there any way i can check the codes without an obd scanner (the thing that checks for codes). Do you think I ruined my engine after trying to start the car multiple times without gas?

My check engine came on last night and stayed on during multiple restarts and also again this morning when I started it. I thought I was ready to bring to the dealer Monday morning but the light "magically" went off while driving today. What could cause this? And finally would there be a code stored that the dealer could check?

View 2 RepliesToyota - Sienna :: 2000 - Check Engine Light Would Come At Times And Go Away / Multiple Error Codes
I have a 2000 Toyota Sienna that has had a check engine light for a while. The light would come at times, and go away at others, with prolonged intervals (days, weeks, months) with or without the light.
Suddenly it started losing power, especially on hills (even a small hill). The codes I read are (I include code interpretations from internet search):
P0300: Random or multiple misfire.
P0301: Cylinder 1 misfire.
P0304: Cylinder 4 misfire.
P1130: Air fuel sensor
P1150: I have not found a problem definition for this code.
Might these codes be indicative of a particular problem, or is each problem more likely a problem with its own cause?
Ford Super Duty (1999-2016) :: 2000 F250 V10 - Multiple Misfires / Engine Shakes Quite Noticeably Over 40 MPH
I have spent alot of time looking through threads about v10's misfiring and have not been able to resolve my issue. I recently purchased a 2000 v10 f250 with about 220000 miles on it I bought it knowing it had one miss fire but now I have a total of three. Te truck has no problems accelerating but at a little over 40 mph the engine shakes quite noticeably and after 60 i5 seems to smooth out. After alot of reading I replaced all of my plugs and ignition coils, ran a can of sea foam through my gas tank and my intake with no change to the miss fires. I have started my trials with the fuel injectors by switching them from miss firing cylinders to ones that aren't. Some other information is my truck has no egr on my intake.

I have a 2006 F150 4x4 5.4. For a long time it idled poorly and would take 2 trys to start. Today it started shuddering and the engine light came on. The engine light went off but it still runs rough and smells of gas from the exhaust. It is not very drivable and I can't afford to take it in. I have lots of mechanical experience but not with this electronic junk and need diagnosing the problem. I have a code tester and this is what it said.

Passat (B5) :: 2003 W8 - Check Engine Light Came On
I have a 2003 W8 and the check engine light came on today for the cam b sensor... The car has had no problems and drives fine, I do not quite get why all the sudden it is on, and before I bought the car, 2000 miles ago the cam sensor was replaced for inspection, and I drove it for 1000 miles, and now the mil is on and it is running a little ruff... Where exactly on the head is it located? which head would have cam b sensor? I really do not think it is bad again.
View 2 RepliesPassat (B5) :: 2003 - Check Engine Light Coming On
I have about 75K on my 03 1.8t on started having the check engine light coming on in the last few months. The dealers diagnosis was that I wasn't tightening the gas cap enough but I don't believe that because I do at least 3-5 clicks when I close it. I'm a bit baffled. After the last time I filled up at the gas station, I noticed the cap was loose so I've ordered another cap thinking the last one has lost its ability to seal properly...
View 3 RepliesPassat (B5) :: 2003 - Check Engine Light Came On And Car Is Running Really Rough At Stops
I have an 03 Passat with about 70K miles on it. My daughter put rug in it this morning (about 7 gallons) and since then the check engine light came on and the car is running really rough at stops. While accelerating, it seems to be fine. It is also getting about 10 mpg less than normal. MIL codes: P0300, P0301, P0302, P0303, P0304, and P0171. He said the P03xx codes were related to misfirings on each cylinder. The P0171 is a bank 1 failure (?). What do those codes really mean and could they be related to bad gas? Sent her off in my TDI JSW so she's not out on the highway if the Passat decides it doesn't want to go anymore.
View 6 RepliesPassat - Volkswagen :: 2003 - Check Engine Light Is On / Code Is P0778
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).
