Excessive FAST TPS

[dhegge]

Guys,

I have noticed that the TPS at idle on my car has slowly been creeping up. It is now 27 at idle. Is this too high? Does this indicate a failed sensor or some other problem?

I realilze that I have to set the off idle TPS to a few above the base TPS number, but does it matter that it is so high?

Just curious,

No, it doesn't matter what value you start at as long as you enter the off idle value. FWIW my idle value is 29.

It really won't matter in the long run what the TPS value is at idle, but the fact that it is changing is odd. Where did it start, and why is it changing?

Is it loose?

TPS is really only used for acceleration enrichment, so you might have to adjust AE vs. TPS position a bit.
