Engine rpm will drop down to about 600 and idle really rough and smell like fuel normal idle is around 800. I unplugged maf and engine seems to run better until it idles 1000rpm and had a constant misfire almost like its running on 3 cylinders. I suspect ecm it looks ok with no bulging capacitors and no hot spots. Fuel pump looses prime every other day. I suspect the pump gets hot and starts to loose its pumping abilities. Iac almost kills the engine when unplugged. Tps does little to nothing when unplugged. Maf unplugged seems to make the truck run better but my experience with an 01 mustang an unplugged maf basically stalls the engine or does stall the engine. Those options are in my head or I have a wire beginning to open or short causing low voltage to the pump. While the truck runs like garbage at idle if you start driving it tends to run better like the pressure goes up but still seems low on power and will begin to run bad when idling again. Maf iac and tps and fuel regulator have been replaced a year ago. every once in a blue moon if I let the truck idle for a long time then drive it, it will throw a lean code any help would be a great way to go id rather not go full parts cannon and would like some ways to test these things or if anyone has had a similar issue with anymore ideas.
New engine, iac, tps, map, fuel pressure regulator, injectors, coolant temp sensors(both), plugs, wires, intake temp sensor, o2 sensor, intake manifold gaskets, pvc valve, checked for vacuum leaks recently <all done within the last year
Fuel filter, coil pack, transmission, tranmission vacuum regulator <Within the last 2 years
