Been reading your threads and found them helpful. I have a 1990 5.0 xlt bronco that would stall when stopping caused by a faulty egr valve stuck in the open position, i replaced that and it seemed to help. The truck is not stalling now (though it has once), but I’m having near complete oil pressure loss when the truck is warm (not cold) and slows to a stop. Maybe a bad egr Position sensor or evr valve?? Not sure if the oil pressure is a problem of it’s own (worn bearings) or Stalling related. Also replaced the IAC and it tested good. Recently replaced all my old vacuum lines with and only noticed this problem since I did that. Might be vacuum related? I think the vacuum system is somehow trying to kill the engine when stopping with a warm engine. Also, when I accelerate hard smoke comes out of my hood near the air filter housing. The engine is not overheating however and I think it may be exiting out of the air filter. Any thoughts or advice would be GREATLY APPPRECIATED. Thank you.
