Random Misfire??????? So my new ls1 has been misfiring since i installed it with a cam and headers and still not tuned but i changed all the spark plugs, Spark plugs wires and changed the coils and still misfiring. I scanned it and i still have a random misfire?? The code was 300. So im gonna check on my o2 sensor later today. Has anyone every seen that code before???
what size cam do you have? Many engines will throw a misfire code because the engine doesnt know it has a cam in it and thinks its misfiring coupled with the fact the motor shakes more now. you may think you have a problem when in reality it just needs a tune

Thats what my buddy told me i just didnt wanna waste my time and get it tuned with it misfiring but i got a 230/236 600 lift 114ls and some LT headers. I'm taking it to EFI Alchemy to get it tuned so i guess i should call them and see what they would suggest to do
