Do you mean the idle drops when you put it in gear? Or does it have no power when you press on the accelerator? Have you pulled codes since you changed computers? Did you change out the wiring harness and sensors too?

Yes we believe we may have found the problem it's the relay all was changed the wiring harness. Sensor, computer, everything we even went as far as to cut the exhaust. As soon as u go from park to reverse or drive it looses power. Idles great.
