need help with swap 4.3-5.3

a heat gun/paint peeler and a pair of gloves will be your friend.

i have done it and it wasnt a deal breaker for me. im 6'6" so that probally helped reaching all the way through the engine bay ;). on a serious note, its no biggie at all, just start at the batter side of the harness, flop the passenger side connectors over the motor, then strap it down to the intake and start pluggin away. i cant remember if i zip tied the harness to the fuel rail or tried to push the loom retainer in its factory spot.. eitherway it works. just make sure the harness is away from headers ...

Nice!

looks good. How does it drive?

drives good, but since i swapped the harness it idles real low and smells like its running rich, i think one of the o2 sensors is goin out or somethin, it did it all day today with no cel, and finally when i was driving home the cel came on so now i can see what the prob is i hope....another trip to auto zone!!

ok...same codes coolant temp sensor, and o2 sensors.....and now when the truck is warm it doesnt wanna start?....i had nelson turn off the back o2 sensors they dont need to be plugged in for grounding purposes do they?

Nope, no need for the sensors or wires at all once the codes are turned off.

well....i dont know whats wrong then
