Sorry this will be long winded. I pulled the 5.3L from my single cab and replaced it with a H/C 6.0 that I built. I used the old sensors and harness. After about 2 weeks of driving it popped the codes. The sensors where changed with known good sensors and them continued to pop the codes. I then went down and bought 2 brand new sensors and a harness from the Dealer. I started driving after the replacement and the silicone TSB treatment, and the codes popped again. I have sold the truck to a marine, and he will be driving it 1000 miles home. I really need to try to get this fixed by Friday night or he will be driving home a truck with this issue. I have had the codes before in other LS cars/trucks and did the above and the codes went away and the problem was solved. This is a 2000 model truck so I'm unsure of the issues the OS may have in it. What do you guys think my next course of action should be? PCM replacement? Drive it off a bridge? LOL



Thanks in advance
