what are the possible causes of the random misfire, I have installed long tube headers , high flow cat's, cat back system, whisper lid and throttle body and that's all, I don't think any of those mod's whould start a misfire, the car was running fine up until today. You can totally tell the car is misfiring now in the way that it is running. What can I do to fix this problem, do I have to take the car to be serviced and diagnostic tested at this time or are there some things I can try first.
The most obvious is to check for some type of unmetered air getting in past the maf,around the TB etc. Less likely is a plug/plug wire problem as that would most likely cause a cylinder specific code. If you have access to a scanner watch the misfire counts on all cylinders and see if it is more predominant in certain cylinders than others,hope this helps.
