Momentary Loss Of Power

Good Morning All,
I have a 2002 F350 4X4 Stock, with 90,000 miles or so. I have recently had the cam position sensor replaced as per recall. A week or two before it was changed we went on a trip and I noticed a momentary loss of power when on the interstate. It acts as though you just take your foot off of the throttle. When this occurs if you let off of the throttle and re-engage it will pick up. it does not occur all of the time and sometimes it does it several times in a matter of an hour. The check engine light never comes on when it happens and it does not matter if I am pulling a load or not. Then I noticed it never did it when it was on cruise. So the next time it did this I quickly put the cruise on with out adjusting the throttle and it picked up. Has any one ever ran across this. I am thinking it may be the throttle position sensor going bad. Any input would be much appriciated.

the CPS should only cause random shutdowns. since this happens randomly, it probably something electrical, not mechanical.

if you see a light at the end of the tunnel, it's probably just a photon torpedo

Bump this topic back to the top.... I have a 01 Stroke doing this as well and would like to know where to look for a fix. I have replaced the CPS within the last year or so but it was the black one. I paid for it out of pocket because I had not received the recall notice yet. I bought one from Carquest which actually had a CPS inside of a Motorcraft wrapper inside a Carquest box... Go Figure. Thanks for any help.

Windshield Wipers?? New one on me, but I guess anything is possible. I will look into that International part number and see what that does for me. Hopefully it will be a quick fix. Thanks pinkfloyd!

Just a thought.. Would the throttle control servo cause this? How would I go about checking the resistence on it? Thanks
