I have a 1994 F150 with 5.8w and E4OD. Starts up and idles great but sometimes is hesitant to accelerate, tach will bounce up and down sometimes, and will stall out when coming to a stop sometimes. Didn't do it to me yesterday at all then today on the way to work did it 3 times. Got codes 10 and 536 but not sure if they have anything to do with my problem. Anyone know what could cause this?? Thanks, Jason.

Code 10 is a "Separator" code
Code 536 indicates the "BOO" switch is not working correctly.
Code 536 shouldn't affect idle or stalling. Has the truck had a tune up?
I would try cleaning the IAC valve 1st. Start with the EASY stuff first.
Brand new IAC, TPS, 19lb injectors, fuel pressure regulator, fuel pump, and thoroughly cleaned throttle body and intake plenum. Ran through whole harness for loose or broken wires and cleaned and greased every sensor plug just because I'm OCD...lol.
