help started running bad 1 day

[machplus2001]

I have a 02 f250 with manual 6 spd. I went to drive home from work and it died I noticed it took longer to start and on the way I lost all throttle response. I pushed in the clutch and it idled (poorly) shut it off and restarted same problem did it again and seemed to be ok . had cam sensor replaced and it is still doing it. The truck has 140,000 miles .... any ideas? by the way when it was running badly i could push on the pedal and nothing would happen

i have an 02 f-250 and mine is doing the same, it is at the ford dealer now, i bought an idm and put on it yesterday and it isnt fixed yet, i talked with a guy yesterday and he said the harness could have a short or burnt place in it. i called and told them at the ford place and they are going to check, since they havent found out what is wrong either.... mine is idling rough and doesnt have any power they told me the injectors are fine tough.. i'm still in a mind boggle on what it is. that idm part was expensive for it not to be the problem

[machplus2001]

I know what you mean parts are to expensive to just be throwing them on. A friend had the same problem and it was his cam sensor. I just had that done when this happened and it did not help.if you could let me know what they find it would be great. Money is tight and I can fix it I just can't diagnos it. Your help is appreciated.

if you can push the throttle in all the way in its very slow to respond and takes forever to gain power and basically barely runs, sounds like the injector pressure sensor. That's about a $200 sensor but most likely that's the problem. Mine just did that about 6 months ago.

[machplus2001]

When the truck acts up ( it's intermittent) I get no response, I push the pedal to the floor and it barely idles and does not come up at all. shut it off restart and same thing shut off again restart and it will respond, it's still not right but I can at least make it move.
Thanks for the info

hmm... someone else will have to chime in. Typically if its a cam sensor your truck wont even run. And the ICP sensor will do what your describing, but typically when those go out there out. Are you running a stock program no chips etc?

[larz18]

you can test the voltage between the two pins on the ICP sensor.
voltage should be between 4.5-5.5 volts

[machplus2001]

This truck is stock no chips no mods of any kind

[larz18]

do you have a scan tool and have you scanned the pcm?
i'm still banking on the ICP sensor :-)
