i bought a 92 mustang 5.0l and am having trouble with certain codes. I have checked this out quick and came up with 6 codes. it is a 92 mass air motor stock.seems to act up when pushing on clutch peddle, revving up and down but all codes come up right away when i start up car engine light comes on few seconds later. here are the codes 63 tps low, 22 baro/map range, 34 evp/pfe high, 51 ect ect-40f, 53 tps high, and finally 54 act/vat-40f. any ideas would be greatly appreciated

That's pretty much all of your sensors.
It's probably something else causing it. Do you have the EEC ground hooked up? It connects to the negative terminal on the battery.
My guess is that it's a wiring problem...

code 63, check you base tps v should be around .95-1.05v if not and you have 5v ref , bad tps / code 51 ect v should be about .60v hot ,sounds like sensor unpluged or open, if sensor is black, throw it away and get one from a ford dealer. it almost sounds like the black wire with a white stripe = signal return is open, it grounds inside the pcm, you can externally ground it but thats not the fix, its late and ill check back tomarrow, big G
