I'm having the same symptoms. 1991 VR4. horrible hesitation between 2k and 3k. Hard start. Car runs OK when fully warmed. Getting CEL for volume air sensor and coolant temp sensor, which have both been swapped with known working ones.

FSRMotorsports has swapped and tested all sensors and ignition items so far, although the wires may have been overlooked. I'm swapping in a known working used pair tonight and will report back tomorrow.

I'm looking for a working ECU to test in my car, and will be bypassing ECU<->sensor wires this weekend.
