Hello,

'06 cc D/A sb 4x4 LBZ. Today when driving 70mph on the highway the MIL light came on and stayed on. Drove 150 more miles stopping and shutting down at least three times. The MIL light came back on each time. Got back on the highway tonight MIL light still on, went to pass someone and a ton of WHITE smoke came out the exhaust (just a huge fog) and the light went off. Any ideas?

Thanks, Tim

Moosecounty-
Might be a fuel filter??? When starting your truck does the change fuel filter inticator come on? My LBZ blew white smoke due to a bad fuel filter...no codes or anything...went into some kind of limp mode and wouldnt run above 200 RPM's! Best of luck and keep us posted!
