We just installed a new engine in our '86 T-Type and the car is not running right. According to the Scanmaster, the O2's hang out in the 100's, the cross counts are very lazy, and the TPS reading does not change when the throttle is moved. The car runs, but idles poorly.
We've changed the TPS (and verified its output with a voltmeter), the chip, and the ECM. All sensors (including the AC Delco O2 sensor) are new.
What could cause this? A faulty ground?
