Same problem here too except mine is the mandom misfire. I read somewhere on the net that our cars dont like aftermarket CAIs and may need tuning due to the A/F ratios going lean. I think it was on ZZperformance or something. Did your mechanic do a leak down test? Could be a bad valve seat. Also do you have a lightweight under drive pulley?
