2nd Gen stalls when accelorator depressed quickly
New Member. Purchased RX7 2nd gen ITS with no engine or radiator. Car originally built by Rotary Performance. Installed engine from a running donor car with good compression. Replaced fuel filters in fuel cell, injectors, checked oxygen sensor, pressure sensor. Fuel pressure at 45 psi and increases when throttle pressed. Throttle body is modified from original race car. Swapped ECU, MAF and engine wiring harness from donor. Car idles nice and will rev to redline if accelorator depressed slowly. Quick depression of accelorator and car stalls. Dyno showed it to go very lean. Checked grounds. I am stumped and I want to go racing. I would appreciate any advice.
