Did a tune up on the truck....new cap, rotor, wires,plugs etc etc.
Drove it for a few days, then did some work trying to get rid of a DTC, so I was tracing wires and testing connectivity between the PCM plugs and the Coil Module connectors etc.
Everything tested fine, so I plugged everything back together, then the truck would only run for a few seconds, then die.
I have spent days going over every system, harness, plug etc etc and to no avail.
Decided to pull the plugs and check them out...they looked wierd...wetted and carboned.....so I threw in a set of Champions and she runs like a top! Never again will I put those platinum fancy smancy plugs in again......They were all the parts store had....next time, off to another store......3 days wasted!!!
