Missfire update For those of you that dont know, sometime ago I posted about an off idle stumble...and a high speed misfire at about 5200 rpm. This is what I have done to solve the problem,maybe it will help someone out there.
Last friday I took the car, a 93 t/a to the dealership where I work, and ask to have the back 2 plugs put in because I couldn't reach them...and put a new set of plug wires on, and to have them do a upper end injection cleaner (GM top engine cleaner) not the stuff you pour in the tank, tried that and did not do a damn thing!!! My plugs were burning good except for no. 1..3..5 cyl were very lean, no brown at all. Well no more stumble...missfire...and idles like a brand new monster should. So maybe people should check to see how there plugs are burning they can tell you alot!! Hope this can help someone just my .02 thanks.
