I I have a 2005 Chevy Silverado 2500 HD four-wheel-drive 6.0 gas engine automatic the engine has 70,000 miles and the trans is rebuilt. The truck has rust and I’ve given up. The truck has a knock sensor code and some other crap codes.
MY QUESTION IS, do 01 02 03 HAVE LESS RESTRICTIONS ON THE CHECK ENGINE LIGHT EMISSIONS , KNOCK SENSOR AND ALL THAT CRAP? IF I SEAP MY 05 ENGNE TO AN 03 WILL THERE BE AN ISSUE WITH CODES.
The 05 seems to be throwing a code constantly. I have an 04 and an oh one that has no problems and passes New Jersey inspection without issue.
Thank you
Ed
