Engine Performance problem V8 Four Wheel Drive Automatic 200000 miles
My Z71 is backfiring through the exhaust and missing at mid range RPM. I have changed the plugs, wires, cap and rotor also cleaned the EGR system and installed a new temp switch all with no results. There is a 20 amp fuse in the box under the hood that is listed as Engine that blows every-time I put a new one in - could that be related to the problem? Anyone know what that fuse goes to? It is not a ECM fuse.
Thanks for any help you can give!
have the same problem?
