throttle position sensor

[dmattingly1]

I been having trouble with my 1992 FORD F 150 5.0 MPI it seems to run good unless you push on it a little and when it hits second gear it just flattens out and tries to die.I replaced wires, plugs , cap, map sensor, oxygen sensor, had the converters checked and I'm still having same problem.Aso replaced fuel filter.I'm getting a throttle position sensor code out of computer but I've never seen a tps create a problem other than an idle problem and it idles perfect. I was wondering if anybody had encountered a similar problem.

Welcome to the Zone!

I would say change the TPS. The computer isn't liking something with it.
The TPS doesn't only monitor the idle position but it works through out the entire range of the throttle.
Good Luck
