thanks everybody,i re-posted in a differant forum, sorry about that

 

the 04 lb7 engine didn't have the egr crap. are you sure you have a lb7 or an lly engine? check the 8th digit of your trucks vin # if 1=lb7, if 2=lly. oh yea, welcome!

 

hey thanks for the reply the 8th digit in the vin is a 1

 

then your truck does not have the egr. you need to see what codes are active on your truck. you can go to a parts house like advanced auto or autozone, they should be able to check your truck for codes. just write down what codes you see and lets us know.

 

p0307 cylinder 7 misfire p1404 exhaust gas recirculation error egr #2. that was the codes from a oreillys autoparts.

 

check the wiring harness that is running across the altenator bracket to see if any of the wires have damaged insulation on the which can cause a short. if you find any, you can repair the wires with butt splice stac-on and for added protection against water, use some shrink wrap insulation. this can be found at radio shack. you might find it at orielly's.
