EGR Valve Position Sensor

[lawman212]

I have a post for a stall and fuel mileage problem on my 1989 Bronco with a fuel injected 302. I just picked up a new Map-Sensor and will install it within the next few minutes and plan on changing the O2 Sensor next week. I was wondering if the EGR Valve Position Sensor should be changed as well in connection with this problem. I don't plain on testing the old one it doesn't look as if it's ever been changed and would rather just install new parts. But if this part isn't connected with my problem I would rather change it out at another time for buget reasons. I started changing engine parts out right after I got my truck that looked old and beat up to prevent any problems plus it makes the engine compartment looked well maintained. It's a Marine Corps thing I got from driving Tanks and Trac's. If it looks beat up change it or you will be changing it out when you don't want to or have to at the worst time.

have you checked for Codes yet? if not read this by an expert, hate to see you spend $ on parts right now, save it for going out.

a pure guess from here is fuel pressure; run a fuel system pressure/volume test. could be fuel filter, pump,an injector, etc.

another guess is the TFI Module or Hall Effect Sensor esp. siince it stalls when hot and runs when cooled down..sorta like an ole horse like me
