    I'm replacing my TPS (throttle position sensor) because the Check Engine light came on, and when I plugged in my GM code reader it told me my TPS was grounded out (faulty) thats why my idle is at about 2,200 RPM on my tach. Does anybody know what a normal (when engine is at temp) idle seed is supposed to be. 88 350 TBI headers and true duals. Thanks alot.

    Yea. I always heard for an auto, that you should put it in drive and have someone hold on the brake while you adjust the idle instead of doing it in park. Something like 700-900 RPM I'm sure would be fine.
