RV need help Chevrolet forum was a waste of time....

A friend had a misfire issue on his pickup and after beating his brains out, he brought it over to me. This was a Toyota pickup but a computer gas engine is a computer gas engine. Anyway, he told me he changed the plugs and the computer started throwing misfire codes about a month later and would stall when hitting big puddles (he's a 4wd freak like me).

First thing I did was pull every coil pack, wire, resistor cap and then the plug and carefully inspect. On #4 I found that the wire was pulled slightly out of the plug cap and the hot firing electronic ignition blew a hole through the resistor plug cap and was arcing to the inside of the valve cover (hemi style plug in center of head engine). He was about to blow 500 bucks on new injectors. New cap and wire and he was rolling, no issues in 6 months. BTW, it took about 20 minutes of running for the computer to get it's **** together after the repair was made, even though the CE light was off.

Take it for what it's worth and I hope it helps.
