TPS Part Number?
My S2 cab has developed a slight hesitation under acceleration and deacceleration. I changed the spark plugs and noticed fresh oil on the threads of the spark plugs. I believe the engine was overfilled with oil recently by a "911 shop" that converted the lighting to Euro specs.
In any case, I went ahead and changed the cam cover gasket, o-rings and J-tube to prevent the oil from reaching the plugs. However, the car still hesitates and after changing the DME relay I'm inclined to think the TPS (throttle position sensor) is at fault. I doubt it's the fuel filter because I believe it was changed around 10K miles ago (30K is recommended). FWIW, the ignition control module was also replaced at 126K.
Anyone have the part number for the TPS so I can find one locally?
TIA

Exactly it! Dealer says it needs to be special-ordered and will take 7-10 days 
I'm thinking of ordering directly from Mittelmotor, or someone like that.
Who do you recommend?

No clue, I usually get stuff like this from the local dealer... however, I've heard good things about Van Zweeden, <a href="http://www.v-zweeden.com" target="_blank">http://www.v-zweeden.com</a> - maybe they could get the part for you as well?

Thanks. I'll give them a try.
Fuel filter was replaced at 120K miles. Car presently has 136K miles. Porsche says they're good for at least 30K, but maybe I should replace it anyway?
