I have a 94 F150, I-6, 4x4, 5spd. No options but a radio. It has been idling goofy for months so I posted a thread and got many replies. (thanks!) I never found the problem and I get no codes. I just turned the idle up a little but it does sputter. I cleaned the IAC but it was pretty clean already. Now it is starting to stall at idle if I turn the wheel and sometimes when I come to a stop. What is with these Fords and idling problems. Somebody has to have a fix. I am getting a lot of gray hair with this truck. Somebody throw me a life preserver!!

Thanks!

 

Sounds sort of familiar. My V8 5.0 has a similar issue. It started just stalling at idle and while stopping, but RAPIDLY progressed to stalling when I am slowing down. Sort of a bad deal when you go to turn a corner and stall in the middle of the road. I checked the EGR and replaced the Oxygen Sensor to no avail. Seems like there are a lot of people in the same boat as you and I on here. Has anyone successfully solved this one?

Check the throttle body gasket . It literally gets half sucked into the manifold. Very common on this motor. this is also a good time to give the throttle body a good cleaning.

 

I am having the same problem but with a few more twist. I am $800 in to mine and thats me doing the work and I am still having trouble.

Mine started out the same and had been getting worse. I think I may be making some forward progress now. Tonight I changed the plug wires and it ran better on a test drive but we'll see how she acts tomorrow. It always seems to change.

I have change everything from fuel pumps to sensors and even a new TB.

 

I just got rid of one of my headaches! I sold my 92 F150! Now I still have this 94 F150 but I cant get rid of it til I fix this problem. I have noticed that it runs perfect when cold but when it gets up to operating temperature it starts the funky idle thing. It will run fine for2 or 3 engine revolutions but then it seems to miss. It will then run 2 or 3 revolutions then miss again. If you rev it up and let it come back to idle it will run for 10 seconds just fine and then start all over again.

 

Check your ignition timing and set to 12-14 btdc
