I have had a constant misfire on threre and five for 4 months. I have tried everything with no avail. Just today I think I have tracked my misfire down. After speaking with Mike I became sure It was an electrical issue. I have Kingsborne wires (3500 miles) and new champion plugs. Compression test was good and consistant, leak down test came back fine, and all gaskets are in good repair, No coolant leak (not a drop), and no other codes. So today I decided to look at the electrical side again. 3 and 5 are on the same side of the same coil. Part is ordered and will be here mid week. If this is not it I am at a loss. Any thoughts...
