Running issues
95 f250 5.8l
Had to pull the head got it running after some difficulty (my own fault though).
Truck will idle at 700-800 REALLY rough then spikes to 1300 and stays there.
Losses power at times, jerks and bucks ect.
I have triple checked the timing - pull spout im about 10-12 degree's (hard to read it but did mark 10) Sprayed starting fluid around engine to make sure i don't have a intake or vacuum leak. I have checked the wiring over and over again. Before i bring to a shop, what do you guys recommend? TPS is showing a code, BUT when i actually look up the code online its some evap code NOT what my scanner says it is. 0545??? I think is the code have to rescan to double check.
I also have just plugged in a NEW TPS (not hooked up to throttle body) I know that if this WAS the issue it should at least solve idle because it just sets every time you start.

Run the codes again... Don't think there is a 4 digit code in 92', just 3 digit. Don't think there is a 545 either.... Run the codes again...
When you hooked up the TPS, what was the Signal Voltage Output in the Closed Throttle position ?
