Cadillac ATS V6 DBW Idle Issue, Throttle plate position rises after start
Idles for 15-60 sec (depending on temp) around 1500 rpms, then commanded and actual throttle body plate position starts rising from ~14% to 30+% before I shut it down at 3.5k+rpms.
Engine swapped into a rail buggy
Pedal position stays at 0% the entire time unless I physically hit the pedal.
Air fuels are normal, engine seems responsive, can be driven but idle is crazy high. No vac leaks have been found.
All idle parameters are oem other than trying to command different idle RPM points
Any help would be greatly appreciated
