A mechanic buddy replaced all spark plugs, all plug wires, and coil pack.
Started getting multiple misfire codes about 2 weeks ago. RANDOM, particular cylinders (4,5,6), Misfires on Startup. Code reader says Severity 2 out of 3.
Mechanic buddy figured faulty coilpack. Took out the cheaper coil pack and replaced it with an OEM one.
Drove the truck a few times for two days. No codes. "Felt" like it was running fine. TODAY, however, all those same codes showed up again. Had the code reader in the truck. Recorded and then cleared the codes, drove home, no new codes.
Any ideas? I'm at a loss as to how to diagnose this.
