I have a FAST EZ EFI system that has a bad sensor on the throttle body. Don't have the time to play with it to figure out which one is faulty. Keeps giving an O2 sensor code. Yes I swapped with a known good one. Asking $600.00 OBO shipped to the lower 48. For an extra $100.00 I will send a Fitech fuel command unit.
Just an FYI. my father-in-law has the same system on his 84 Ford f150 and it runs great. We were able to swap things around for testing. Both harness and computers worked with the other throttle body. Put this throttle body on and after warm up got the O2 sensor code. Must be one of the sensors on the throttle body.
