Thread: misfire/stumble/ high idle

i was thinking the same thing spark plug gap could be causing the misfire if tooo large have you has aany nitrous backfires that you know of that might be causing this problem

I would be looking into some kind of air leak...

no, i fixed it already tha iacv was causing the high idle, and the spark plugs were causing the misfire

shouldn't the plugs be gapped at .44 for N/A?

did you replace the iacv or clean the iacv

i just replaced it, i had one under warranty from my old car so it made more sense to just get a new one
