I’m experiencing weird misfires when accelerating 2nd & 3rd gear while under load between 2500-3000 rpm then it clears up. Almost like a revlimiter feel for a moment and then it clears up. It doesn’t happen every time, just sporadically. Car is bone stock with the exception of the PCV valve mod I got from a forum member here few years back, which works flawlessly. 6sp manual trans also.
