Well after trying 8 different TPS's I snagged from the junkyard, I finally found one that seems to be working half decently. I believe it was from a 87 or 88 N/A stang. I put it in yesterday and set the idle with the engine cold and drove home fine with no codes and again to work this morning with no codes and no sputtering and a fairly steady idle. AT lunch I made a TPS test harness with some old connectors/sensors I snagged from the JY then soldered some alligator clips to the wires. I warmed up the engine and reset the base idle. TPS reads 0.966-0.970v with IAC unplugged and KOEO. The only problem I forsee is if I pull the throttle linkage all the way to end of travel I get a reading of 5.21v which I know is high...is this going to cause trouble when I'm at WOT? or will the conputer compensate and just assume its at the high end of travel? The replacement part from ford has a part number of CX 1135 and costs a whopping $66.43CAD (although I could get a discount if I goto a different dealer). Think I should stick it out with this one or drop the moola for a new one.
