At cruising speed, steady throttle pressure everything ok. Excelerating it act like it is running out of gas. It will search then act like it is choking on itself then surge, so on, so on. Idle is okay. Took my original and put it back in, road tested, and the engine was back to normal and the torque would not lock up. So there is definately a programming issue. My original (87) had every pin in place on the computer, the 86 has 10 pins missing.
