Started about a month ago with a cylinder 7 misfire. Replaced my lifters after inspecting both lifters (lifters had very light wear, no problems rotating) and camshaft (found no wear on camshaft). The lifters I put in were all non-MDS. The car has a 93 octane diablo tune on it. I've also got entirely new spark plugs. Cylinder 4 now has a misfire code in addition to a random misfire code I got on initial startup. I have a log file from my diablo tuner but cannot attach it to this post. Could someone inform me how to attach the file and also, more importantly, help me figure out whats causing my misfire?
