It tried everything I knew to mess with, but It ended up being the damn spark plug gap. I'm pushing 9psi, and .034 was too big of a gap. I talked to a guy that races and builds fox body turbo cars and he said to go down to .022.... it erased all of my problems that I spent countless hours chasing down. I'm currently at .026 and it's running perfect. I may be able to open them up a few more thousandths, but the time it takes to regap them all isn't worth the minute power gains that I'd get. .034 ran like crap, .026 runs perfect.....good enough for me.</p></blockquote><p></p>
