to anyone pulling engine misfire codes or just having engine problems.. your solution may be to have a leakdown test on your engine. Ask your mechanic he will know what to do.. But this can easily pinpoint a engine problem.

I was having misfiring codes but wasnt rele having problems with the car driving.. Seemed to sputter a lil below 2000 rpms and choke a little but nothing to bad but it does not do any of that since ive got her fixed. Basically i had a little AIR LEAKING OUT OF ONE OF MY CYLINDERS AND HAD TO GET A couple new valeves and new valve seats. It didnt break my bank but if you gotta take your block to a machine shop.. that can get costly.. Anyway my mechanic charged me about 1700 but he got it running back to normall with no cel codes. I came to the conclusion that this happened bc i hit the rev limiter a couple times and who knows how many times the people did before me.. But if you want something to be right then your gunna end up doing it yourself

 

Hitting the limiter will not cause valve problems, guaranteed.
