Alright...I cleaned my throttle body again, and forgot to disconnect the batt or pull the fuse. Put it back together, and started the trailblazer. It was then I realized I had not disconnected the batt. High idle, then down to 300 or so rpm,,spitting and sputtering (CEL,stabilitrac, and loos of power light on)
Disconnected the batt for a few min, then tried it again, all seemed fine after I reconnected and started it up. Took it down the road. Ran great till I hit about 3500rpm. It then lights came back on (CEL, stabilitrac, and loss of power) and dropped back down to 300 or so rpm.
Limped it home, turned it off. Now when I turn the key, I only get a CEL. Trailblazer will not even turn over. Do I need to do a PCM relearn? Or??
