1996 f250
Hi everyone im new here,im having problems with my 1996 f250,when ever i accelerate the truck missfires and the check engine light comes on and when ever i pull over the rpms bounce and whenever i turn it off and re crank it everything is normal till it does it again.i have replaced the ipr the icp uvch and pigtails ive replaced injector orings but i still cant find the problem the truck has 358,000 miles on.any help is appreciated
i replaced the cps as well still no fix.I unplugged the idm and my prongs on the plug were dirty i cleaned them up and it got rid of the surging issue i had but it didnt fix my acceleration problem,i did do a fuel bowel delete a while back and noticed that my fuel pressure is at 20 while at idle and when i hold the rpms at 2000

Fuel is 20 during crank and not drop below 45 when running
Maybe fuel pump went and some fuel going into the oil.
Good read if not using efuel

so i changed the fuel pump,fuel pressure is at 65psi but i still have an issue of a check engine light coming on and i had no throttle response after stoping at a stop sign i put my foot to the floor and rpms didnt even go up possibly throttle position sensor?
edit.i unplugged the sensor and plugged back in truck did great got up to 85 without any issues dont want to jinx myself so im gonna take it out again in a little bit
