'05 6.0 Stalling?

[ahbennett4]

(Automatic Trans)
Occasionally while driving the truck will stall at idle, or after me letting out the gas.

-With idle, I mean the truck is in Drive, and ive let out of the throttle.

Also, occasionally the trucks RPMs will highly increase, a grand or 2 for a split second, and then go away?

It typically happens whens its cold out.

Any ideas why this is happening? I havent taken it to the dealer, but a master tech told me it could possibly a Camshaft Sensor?
He mentioned these are so s**t on Fords, he keeps a sensor and 10mm wrench in the glove box.

this sounds like a possible ICP sensor and connector issue...wiggle the ICP wires at idle and see if the RPM changes at all...If the rpm's change when you wiggle the wires replace the ICP and connector...if it still stalls you will have to get a scan tool on it to monitor some data.


As for the stalling when let off .....that sounds like a sticking IPR...but could also be a ICP sensor/connector issue too.


CMP is not likley to raise the rpm's but can cause a stall.....hope this little bit of info helps ya.
