Just the other day I had my mechanic check the TPS (and clean the throttle while he was there). As I had thought, an adjustment was necessary.

HOWEVER!

The TPS was so far out of range that an adjustment would have been pointless. As I understand it, the TPS should be at 10 - 12 KOhms when closed, and subsequently should be at 3 - 5 KOhms when open.

My mechanic reported that my TPS ranked in at 3.6 KOhms open (fine), and at 0.5 KOhms closed (waaay not cool). Is this right? At that point, it seems to me that my car would have some serious performance issues when approaching WOT, but everything seems to be pretty satisfactory. On cold mornings, there is an idle fluctuation for approximately 5 seconds, and a very slight idle pulsing on most days. He suggests TPS replacement. Anyone share his opinion?

I also pulled a code 37 from the ECU (number 2 O2 sensor inoperative). The idiot light only comes on during those cold mornings, not too long after the idle fluctuations. I realize that the O2 sensor issue may sound unrelated, but both the sensor and the TPS help control a/f mixture.

After the throttle cleaning, the idle pulsing seems to happen less often, and I have yet to see the return of code 37. Performance seems slightly smoother as well, but that could be nothing more than placebo.

Since my car runs *well* and I haven't seen the idiot light come back on, should I be concerned about about any consequences from my faulty TPS in the near future? $0.02, anyone?
