i used to love my 02 monte until one day i put some bad gas and it started missing bad. i figured id put some gas treatment and let the bad gas run out. Ok the bad gas ran out, put some fresh good gas with good gas treatment, ran real good until i got home. Next day it was at it again. I took it for 2 dif. diagnostic and they both said the same thing,( CYLINDER 1 MISSFIRE), so someone sug. a tune up so i changed the plugs and wires, but still missing. Then they sug. to change the cylinder 1 coil pack and still missing. Now im very frustrated. All wires and plugs are good and new coil pack. Went for another diagnostic and then it said (RANDOM MISSFIRE) then someone suggested use seafoam. Used that and no better. Now someone is suggesting a new fuel injector or new module. i am ready to sell the damn thing and i just got it amonth ago. PLEASE HELP ME ANYONE BEFORE I SELL MY DREAM CAR FOR NOTHING

 

Hello, welcome to the forum....


I would run with the fuel injector. It sounds like you have replaced everything around it, not much more to go wrong from here..
