2005 Chevrolet Express 1500 5.3L MIL Lamp on
Afternoon all, We have been chasing this code P0230 for a while. We replaced fuse box, cleaned all connectors, its good for a few months and comes back. Also we replaced the fuel pump. Anybody have any thoughts? I must be missing something??Thanks, Steve L...
