06 Cobalt SS P0171
I've had this issue and its preventing me from passing SMOG in CA.
Car is stock
Took the car to the dealer they updated the Software per TSB
Took apart the intake cleaned the MAF, sealed it back up tight.
Replaced a cracked vacuum line on the boost controller
Replaced the Fuel injectors, noticed a oring was torn on one of the plastic isolators, replaced.(Might pull it back apart and replaced the other 3)
Replaced Fuel Filter
Replaced 02 sensor
Car is @ 90k I'm thinking about cleaning the TB and replacing the seal.
Anyone have another other common place I could check?
