86 302 efi cuts out
I have an 86 f150 w/eec iv 302. It runs fine except when the engine gets around 180 deg or higher. The engine will cut out and barely run. I've checked the fuel pumps, replaced the hp pump, checked the fuel pump relay, replaced the eec relay and changed the ground in case thet was bad. No luck. I've heard about a pip signal problem, so I wired the fuel pump relay to energize with the ign switch. Now I figure there is something that is being effected by the engine heat that either kills the ignition sys or won't cycle the injectors. The ign module is a new Napa echlin module, cost me $80, I don't think that is my problem. I rebuilt the dist with a new pick-up, so that's not the problem. Today I looked over the entire engine harness and didn't find any burned bare or broken wires. I'm on the end of a rope here and goin nuts cuz I can't figure this out!!! Somebody help me!!!

86 302 efi cuts out
Sounds similiar to problem I had in my 1988 f-150 w/302. I first changed cold start scensor ..was fine for a month then acted up again. After that I replaced IAC and havent had problem since. IAC's tend to get carboned up with old age ...was told you could renove and clean up but best to replace. Part I think was 85.00 for IAC, 35.00 for cold start scensor.
