here's a list of trouble codes for the 95 ford.

Don't know if they are accurate or not cause your some of your codes aren't there but the TP is listed there... Makes sense.

Also, check your timing. Running rough and rich with overheating?

Have you tried blowing out the EGR valve? I have a Jimmy that was giving me some of the same problems, eventually engine light came on and it was running hot. Then once this EGR valve was removed and the engine ran for a few minutes to blow out any carbons it ran fine....I was told by the mechanic Chevys and GMC's are known for this, and periodically it should be done. Second thought could be a sensor.
You could aways go into a garage, put on computer or ask them to define the codes that you have gotten.
