Go to the TCCOA site and you'll find the specs on how to re-adjust it to around 0.98v. If you don't have enough rotation on the TPS body to do this, you can take it off and elongate the holes (metal ferrul) with a small jewelers file or drill bit.
I just checked my TPS voltage with the motor off, and it is 0.76V, please note it idles fine. (max voltage is 4.43V)
Will I see an improvement if I do what is necessary to get it up to 0.95V ?
Thank you in advance.
