Im having an annoying issue with my 91 tsi, a cel for TPS wont go away yet everything checks out fine. Im using a 2g tps. It idles perfect right at 700+/- a few rpm, afr cycles right around 14.7, biss is out 1 1/4 turn. Ive adjusted the tps every way I can and still have the cel. I adjusted it to .63v, .48-.52v, adjusted it by continuity and resistance between pins 3/4, total resistance between pins 1/4 is about 4.8k, getting about 4.9v at the plug, I checked the voltage of pin2 at the ecu plug, as well as the closed throttle pin at the ecu and it switches to ground as it should at idle. Im using the 1g closed throttle switch as a throttle stop which is adjusted per the manual, the throttle cable is adjusted perfect, no cruise. I really don't know what else there is. Any clue? Thanks in advance.
