Ok, I put fuel in my Tahoe one morning, 6 miles down the road it was acting funny. It was running sluggish and seemed like it wanted to die. I had it towed home after i got the codes from Autozone. They gave me 4 codes, the fuel pump was making a noise so i knew that would be one. I replaced the fuel pump and 3 codes went away. Now im just stuck dealing with one.
P0308 is the one im working on, Cylinder missfire in #8. So far ived tried Replacing the spark plug, ignition coil as well as switching the entire coil and cable with another one. The missfire didnt move like i was hoping it would.
What else could it be?
Update #1 I just checked the connection on the wires and there is equal amount of voltage coming out of it as the rest wired to the ignition coil. So that tells me its not the spark plug, coil or power going to the coil. Any help
