Angry Need wiring diagram for 3.8 2000 Mustang

My 2000 3.8 Mustang runs great but it seems if it gets hot or on a long run, say 3 hrs or more, it starts to lose power. I have to shut it off for a few seconds pop start it and it runs fine for a little longer. I have to keep doing this until I get to where I'm going. I have a TPS and MAF sensor code coming up, both of which I have replaced (TPS 3 times MAF once) and still the same @#% happens. I think I have some bad wiring. Any way I would like to get the wiring diagram so I can check those wires. Also where is the computer located in the car?

The computer is located under the passenger's side kick panel. What are the specific codes?


'01 V6 5 speed 267rwhp, 385rwtq
'86 GT
'94 V6

The specific codes are the TPS signal and MAF signal are both low. Since I replaced them both and it didn't change (even after erasing the codes, the codes came back) I was thinking wiring.

Well unless anyone objects I think I'm just going to cut out the old wires to the TPS and MAF and put in new ones. I checked the old wires for continuity and they are good, but that is when the engine is cold. Any suggestions?

The specific code is p0122 (the maf seems fine now for whatever reason). So I cut the wires to the tps and put all new wires in, and accomplished nothing. Still have the code and the problem. Any ideas anyone.

Filled it up with gas and it seems to run better. It always seems to run better when the tank is full. Anyone think it could be the fuel pump at 236,000 miles?
I don't know if that would explain the code though.
When it is acting up it runs exactly the way it shouldn't according to a tps code. In other words it has all the symptoms of a bad tps when it is acting up.

Ok. appearantly I don't know what the trick is to putting the tps on. The tps is not rotating with the throttle, it is just sitting there, that's the problem and I don't know the solution.
