Ron,
No, I didn't use any of those stuff, just a straight replacement. I got word from Phil (Fastlane) that those plugs should be fine for my application. I am thinking the MAF may be fouling up. But will get a OBDII reader to scan the code. I tried to get the Service Advisor at the dealer to scan the code for me but they urged me to make an appointment to take the truck in, so no luck. Anyhow, I disconnect the battery to make the CEL go away. Will see if it comes back.
