Hi Guys,
Service engine soon light greets me this morning. Tried removing and replacing gas cap and light stays on. Take it by the Chevy dealership for diagnostic and they are too busy to check it until Thursday, say "keep on drivin', could be 150 different things." Won't be back there any time soon. Take it to local shop and they diagnose a code P1406 No Description Available. There are no apparent problems. Any ideas on what a P1406 is? 97 K1500, 100K mi.
