Hi guys/gals, new to this website and needing help. I have a 1990 mustang gt just built a decent 331 stroker: eagle 331 stroker kit, b303 cam, world windsor jr heads, trick flow street heat, 24lb injectors and matching MAF, all new all new jegs brand hiflow water pump, etc etc...... just a little rundown of engine. all new sensors when i reinstalled engine. But the car runs great when cold but starts running like crap when it gets up to operating temperature. timing is perfect, not overheating. I know i had a MSD streetfire distributor and wires. first start up the car would run till it warmed up them shut down, figured out it was a manufacturers defect dist, so got a new one and this one will actually run when hot and not shut off but runs like crap when at operating temperature. Also dies when coming to a stop at redlights. Any ideas what it could be...?
