engine dies when warm?
I have a 86 f-150 with a 302 FI V8. Here is a summary: My truck kept stalling/loosing all power whenever it warmed up to normal Temp. and whenever I went over 3,000 RPM. I had fuel pump replaced in engine, didn't work, then I replaced the one in the tank. It now runs better under a load (over 3,000 rpm) but it will not run at idle at normal temperature now??
I checked the battery and alternator and both are fine. Once the motor cools back down, it will crank again and run fine until the engine warms up to normal temperature? Does anyone have any ideas what this might be?
