When the TPS is unplugged, the car idles at 1500 and stays there. When its plugged on I get anywhere from 600-1500RPMS. So I replaced it with another TPS. Now the idle is about 500-600 which is still a little too low.

When I rev it hard or drive and come out of gear, it still does that bog down to shut off, but now actually shuts off at times. Any idea on this one?
