lol my name..those were my intentions to go Bo0st but i cant now..my friend marked everything the pullys and belt and put them on the sam way...the miss fires are truly RANDOM the car run fine but when i has a miss i could feel it for a second or 2. the light most of the time comes back after 4-5 day..

 

Does it say how many instances of the misfire fault are recorded? If it's only two cylinders, and only once every 4 or 5 days, that still could be the O2 sensor.

 

[QUOTE=Fabrik8;5519799]Could be a distributor problem too, because that's where the cam and crank position sensors are. This is probably unrelated to the head gasket replacement unless something external was damaged during the install.[/QUOTE

i didnt think of that.. the car runs stong n no abnormal sound from the engine. but im look in to that

i use a obd scanner and i didnt think it has that Feature.. im buy that O2 bug to get out of the doubt..lol
