02 sensors and fuel trims not working HELP PLEASE
Hi guys i need some help. I put a lq4 in my 86 chevy van and have been driving it. it runs "ok" but i finally got the tuner/scanner hook to it and the 02 sensors and fuel trims are not working. 02's are stuck at 450mv and the fuel trims are all 0. 99-06 dbc harness and 03 silverado ecm. my guess is those two are wired or programmed correctly to match together.
