2000 Chevy 3500. Engines dies when idling in drive.
THE CEL came on, but the truck is running fine, except that it has been hesitating like it has bad fuel. I put berryman chemtool in engine. It starts and runs fine except for an occasional bucking. I fear it may be a transmission issue because there is a burnt smell, like a clutch maybe after I park. The ways it's acting, if it were an older truck I'd suspect vacuum line.
