Hey I've got a 96 hatch with an H22, with minor bolt-on's, I recently took off my iac and cleaned it with brake cleaner and changed my plug's. (NGK iridium's) Car ran fine (kept the same idle and ran smoother but then next day I went full throttle and the car cut's out on WOT. It's similiar to hitting redline, but I'm only at 6000 rpm, sometimes it surpasses 6000, but sputters and feel's like it's cutting out. Also I had my FPR set at 50 psi WOT month's before, then I noticed it was at like 55-60 WOT after the "tune-up". I tried turning it down, but it seems the adjusting screw doesn't change the PSI at all anymore. I was tinkering with the fuel filter during the tune-up but didn't end up taking it off at all or changing it. Anyone know what is the cause of the problem? I've got no check engine light what's so ever. Car run's perfectly fine. Only does this on WOT.
