TPS (thorttle positiong sensor)

Installed new TPS in 02 montana and getting unstable idle until rpm's get so slow that engine dies. Engine will run fine anywhere above 900 rpm, just won't hold an idle. Just wondering if there is a TPS recalibration that would sync my idle problem. Anyone with this information?

why did you replace it to start with?
if you had a code what was it?
other than using a Tech II to monitor RPM I cannt find a relearn for a TPS. You could try a battery disconnect.
