Coby7. Your absolutely right!! I agree with you completely.
I just worry about Silvy taking a Calif smog car pulling the smog pump and dropping in a non calif engine. Firing it up and getting crank position sensor error. Then getting low air pump flow error and chasing those two errors down while the engine sputters and idles ar 2000 rpm as Silty scratches his head and starts to plame the PCM based on an Autozone code scanner. Then ends up getting a used PCM or BCM that locks up due to different VIN.
Finaly trying to figure out how to turn off the mil light due to Calif bad air pump, that was not reconnected, because it is not used in Oklahoma.
All of those subttle little oops that you have shared here on yourcobalt.
Now, knowing what we have learned from you, we can look forward to using the Tech2 and doing a throttle possition sensor, crank position sensor, and possibly a VVP / cam position relearn then trying delete the Cali air pump.
Oh, BTW I wonder, does the non air pump Cobalt take a different PCM calibration file? ? ? I dont know.
One good thing though, he does not need to worry about upgrading his cam chain tensioner on the 09
And please excuse me and do correct me with my flagrent misuse of ECM vs PCM.
