Nah I havent done anything to the truck. It has a catback on it, thats it for performance mods and the catback has been on for over 10,000 miles so. All the happened was about a day or so after I filled up I was getting onto a highway on an inclinded onramp and bam, engine loses some power and check engine light flashes, since then its just gotten worse.

They are probably real close to being plugged. One way to check would be to measure the pressure before and after the cat. If it is much higher before, it's probably plugged.
Since you are so close to being stock, I'd take it to the dealer. There is a federal 80,000 mile warranty on cats.

OK guys I got the truck checked this mornin, needed plug wires and an ignition coil, the shop wanted 670 to do the job, needless to say I took the truck back, paid them 100 for the dioagnostic test and then bought all the parts for $130.
The question is, the sheet says coil pack #1. Looking at the front of the motor, which one is that? also, what are the torque specs on the plugs?
Thanks for the help
