Is there's mechanic in the house???

Did that model still have a vacuum line system? If it did, maybe a vacuum leak somewhere?

I'm with C-note... to make an educated guess based on the symptoms air/fuel metering is a good bet. TPS would be the second thing to look at but a CEL is the first to be pulled to see what has failed or given a fault code.

sounds like maybe an airmass unit, it will mix the air to fuel mixture. Sound also lack power on acceleration, poor shifting bogging on acceleration things like that, hammer on it several times and I am pretty sure you will have a CEL light. If not its a bad throttle body, take it off and try cleaning it. Also try doing a fuel induction service to clean the fuel system.

I have a 92 f150 efi 2wd half ton with a 4.9L inline 6. It has an auto tranny. Here is the problem. One day it started shutting off when you give it gas. No one can tell me what's wrong with it. I tryed the tps, icm, map, and the iac. Replaced the fuel filter and nothing works. It doesn't have a check engine light so I'm stumped
