2001 Chevrolet Express 3500 Question: Cylinder misfire on 7
Answer #1DaveJHM June 15, 2011, 22:42Master
Most misfires are caused by ignition issues - such as a spark plug or ignition wire that has failed or has excessive spark leak.
You could also have an injector issue, but I'm pretty sure you'll find your issue on the ignition side.
