sluggish on hills?

[crazyfool502]

i recently went to pa to pick up a car and on the way back i noticed that the truck was running sluggish on the hills in wv! if the cruise was set it would run up the hills like a raped ape but the check engine light would also come on until i topped the hill any idea? it is a 99 7.3 six speed i didnt know if this makes a difference

your cam positioning sensor is going bad. when i went out to tennessee back in Feb. from north carolina, my 99 psd did the same thing, and if i put it under a real load uphill it would studder or missfire. i had the code read at autozone and it came up with cam positioning sensor. its located right under your water pump and takes about 5 minutes to install. they run about $120 bucks and are easy do. by the way my truck did it when it started snowing and i was running empty bed. so don't feel that bad, you were towing a car.

Whoa, whoa........that is NOT typical cam sensor failure........i would highly doubt that is the issue.....

Get the code and get back to us man......ill figure it out from there.....Marc
