Engine Performance problem
1999 GMC Sierra V8 Four Wheel Drive Automatic
my truck had a large vacum leak causing it to miss and I fixed that and it ran fine for a couple days now its missing worse than before and it is backfining I think it might be the ignition coil that is going bad and I took it to the auto parts store and they put the computer on it and it said that but it wont say what cylinder its on it just lists letters and in the repair manual it only gives numbers for the cylinders can yall help me out cuz the auto store wants me to replace all 8 and thats really expensive when its just one or two thats bad
have the same problem?
