Okay I tried revving it in neutral and park, the rev limiter stops it at 4k rpm and no misfire, in 2nd gear it misfires along with 3rd.

Another mechanic told me its due to a compression misfire (if that makes sense, I don't think that's the literal term) and that I need a valve job.


Thank You again for your feedback, it IS helping narrow down the problem.


Thank you so much.
