runs rough with TPS plugged in?

Well, my car is acting up after i changed the radiator and qthermostat housing to a 1g. It barely wants to run now. Idles like crap. Ive checked all my connections and used all the same sensors but those aren't the problem. Ive changed the maf, and cas still the same. Now, i unplugged the TPS and it will idle nice and if i plug it back in, itll barely stay running and die. Changed it and its still the same.

im lost. /ubbthreads/images/graemlins/dunno.gif

Just did a log through dsmlink and the TPS is stuck at 100% no matter what.

Is it stuck at 100 when unplugged?

When unplugged, its at 0% and will idle fine but once i plug it back in, itll run like crap thinking its running WOT on idle.

Well, that tells me that the wiring is not shorted out from the sensor to the ECU. I would just chnage out the TPS.

Sounds like a bad TPS too me /ubbthreads/images/graemlins/dunno.gif #1285 had same issue when I first bought it

I changed out the tps 3 times and nothing worked. for some reason im getting 5v on the ground wire on the tps connector.

Is the +5V signal still intact? Figure out where the short is on the tps ground. Or provide it with an independent ground.
