Hello, I recently picked up an '87 WE4 and having some trouble troubleshooting. So far I have replaced the ECM (and chip), plugs (gapped to .035), wires (8.5 mm), O2 sensor, and TPS (.44v idle and 5.00 WOT). The car has the Alky setup (running 20 lbs boost). I am having trouble finding why the car has a hesitation under load, and when the throttle moves it sets a code 22 (TPS low). I have adjusted the TPS up to .50 volts but the hesitation won't go away. At idle the car idles very smooth, and the readings in DirectScan all look good, with the fuel mixture at 14.8 in closed loop. Any suggestions as to where I might look next would be greatly appreciated. :dunno:
