I recently had both throttle bodies rebushed and rebuilt. The engine idle was erratic before the re-build and now that it's running, it's still erratic. It seems to be opposite of what it should be. Cold starts with low and rough idle. As temp comes up, it smooths out but the RPM's climb to between 650 & 1000. While driving it, the rpm's never come back to the same place twice but will generally stay between 650 and 1000.
I also thinnk this effecting the shift points in the trans.
have the same problem?
