Update I took the secondary throttle body out of the engine bay today, and attempted to remove and check the secondary throttle position sensor. I was unable to get the sensor off because one of the attaching screws was so stinkin' locked up (and already stripped out), so I doused it in penetrating oil. I had to run an errand, so I went ahead and put it back in the car, and it seems to be working again, rather inexplicably. Hopefully, the problem won't resurface! If so, I'll bring it back to this thread. |
