Engine Performance problem
2007 Chevy Truck V8 Two Wheel Drive Automatic 41272 miles
The vehicle is misfiring on #7 & 8 cylinders. Replaced plugs and wires. Exchanged coils and injectors - same problem on same cylinders. Can unplug #1 and #7 will clear up and fire and #1 & 8 will be misfiring. What can this be? Thank you.
