Would start and idle. No feedback from the pedal.
The ford I had. I think an 85 taurus. Worst POS ever created. hated that car. Abandoned it on the way back from college one night. Don’t know where that POS ended up.
Tauruses were disposable. EEC-IV was good even if not everything they put it on was.
A lot of those throttle by wire systems use a variable potentiometer instead of an optical or magnetic encoder to detect throttle pedal position. Once it was started, would the transmission shift out of park at all?
