The TPS Switch and TPS Sensor are used to set/allow a good smooth Idle.. IF the TPS is not set properly, or (as I found out the hard way ) has a bad 'Switch' on it.. then the car will not achieve a stable Idle.. Please check it..
I have just recently received ECU Talk, and a Conzult Cable.. Holly $h!t.. its like pulling back the curtain at Oz.. things get VERY clear..
You've done all the deletes.. are you running a PROM that does not require the AIV's?.. if not you need to change it.
