Help! I was driving my 2007 Tahoe last week and the Stabilitrak shut Off and Engine Power reduced (I couldnt go faster than 30 mph). I cleaned the throttle body, checked the drive by wire plug at the throttle body, and did a tug test on the wires, thinking it was something related to the "drive by wire" system, as I saw on several Tahoe Forums. Everything was fine. I left the battery unplugged overnight and I drove the car for 20 minutes today thinking it was fixed and then the idiot light came back on, as did the error messages with Stabilitrak Off, Traction Control off, and Engine Power Reduced.
I plugged the OBD II in and got a 2138 error code.
I've got a 2007 Tahoe, 2WD, with 76000 miles on it.
Any help is greatly appreciated!
