why can't most of these topics be happy topics. anyway. ok. i need ideas on misfires. basically a check list of things to do to find out what is causing my misfire. i have a very horrific misfire when i get up in my higher rpm range. i have a freshly swapped h22a in a 92 lude and it drove fine with the exception of a bad idle which turned out to be the intake gasket that i put on was not tightened correctly. i know its very hard to diagnose a problem with out being there first hand to see and hear the car which is why im just looking for things to look for. kind of a process of elimination if you will. any help would be greatly appreciated. also anyone that might live in the memphis, tn area could stop by if they wanted. lol. not sure how many luders there are out here if any. or heck anyone that knows the h-series motors.
