93 F150 302 shutters and stalls

May 26, 2004 4 Replies

I've had my F150 since 95,and have been pleased. Heres the problem however, sometime it starts shuddering and loses power at peak load conditions. It will not respond to the throttle, just keeps slowing down. After just a few seconds it will respond to the throttle, and come back up to speed. Here's a discription of what I mean by peak load. Turnpike 75mph into a 30mph wind climbing a gentle grade. If this occures, it's usually after at least 30 minutes of operation.



These are the repairs made reciently. New trans & converter New exaust system Ignition wires, distributer cap and rotor, plugs



3 new injecters

Does anybody have a clue? Jerry


I'm sure there are many possibilities, but I always start with the simple things. I would replace the fuel filter and make sure there isn't any water in the fuel system.

How old is the fuel filter? Checked the fuel tank pickup screen? Texas Parts Guy

Thanks Guys I forgot to mention That I replaced the fuel pumps cleaned the tanks and replaced the fuel filter 2 months ago.

I too always start with the simple things. Did you check the air filter for blockage.

Also, after replacing the injectors, did you disconnect the battery for at least 15 min to reset the computer?
