DTCs 0030,0036,0102,0443 Thrown Simultaneously
I have an '06' Cobalt LT w/105K miles that is throwing DTCs: 0030,0036,0102 & 0443. And though I have replaced both O2 sensors, the MAF sensor and the emissions system Vapor Canister Purge Valve I am still pulling the same codes. I can't detect any performance related symptoms such as rough idling, stalling, any lack of power etc so I'm really at a loss where to go from here in troubleshooting these codes. Does anyone have any ideas such as a TSB etc dealing with these codes being thrown together?
Thanks so much for any help you can offer.
