compression test results
so i'm still trouble shooting this slight miss that i have. i did another compression test again.
1- 180 2- 170 3- 174 4- 180 I know the closer the better, and i read that if theres a difference between 10% then it could indicate a leaky headgasket. does everybody agree these are decent #'s? matt

Numbers look pretty good to me. Tonight I had a miss...turned out I forgot to put one of my plug wires back on after fixing a vacuum leak. DOH! can't always be that easy I know, but after the crap I have gone through for the last month getting things put together I think the good Lord knew I might snap big time if I had a legitimate miss LOL.

Also, hold the throtte open when you crank so it gets a full cylinder of air molecules! Otherwise the numbers will not be right...
