Tps question

[SmashingDsm]

Hey whats up guys I have couple issues first one I had a problem with my tps I fixed it on my Dsm link but it's at .75 off gas pedal reading 1-2% and open is 5.00v reading 100% is the 1-2% and issue I should try fixing or just leave it alone ? Second when it's on idle at 1300 rpms when I put it on gear it goes all the way to 700-800 rpms what could be the issue ? Oh and its auto transmission would appreciate the help thanks

Sounds like you need to adjust your TPS should be at .63 volts which you can log with link without the car running and adjust. As for the 1-2% at idle you need to adjust through link also make sure that your throttle plate is all the way closed seems that your 1300 RPM idle is a bit high.

The idle could be from a few things here is a great list, from tps adjustment, isc, etc.
