2005 GMC Envoy SLE 4.2L Misfire
Posted to GM Engine on 3/19/2009 13 Replies

The car had a rough idle and the client added a fuel injector cleaner in the tank. It didn't change anything and 3 weeks later the mil light came on. I have a cyl # 2 misfire. Spark is good(verified and switched the coil with # 3) and the injector is also good...
