'92 5.8 Rough idle/stalling on acceleration.
I got a 1992 f-150 5.8 4x4 and I'm experiencing rough idle and stall when accelerating from a stop. No check engine light and it does not do it all the time. I assumed it was the TPS but after some research I think I may be wrong. If anyone has suggestions I am wide open.

1) Welcome to the site!
2) Does the Check Engine light work, such as light up when you start the vehicle?
3) Still recommend to pull the codes just to see what, if anything, may be in memory.
4) A TPS fault will usually throw a code. The IAC typically results in unsteady, wavering idle speeds. Some thoughts are to check for a weak coil for the stalling, and perhaps run some SeaFoam or fuel injector cleaner through for the rough idle.
