RPM jumping up an down

04 Ford F-250 with 6.0
On my way to work my truck started doing something funny going 65 down the highway my rpm gauge started bouncing up an down also when I'm idoling at a stop like the truck would rev up like its trying to take off.
Sorry for such little info any ideas

Re: RPM jumping up an down

check your icp like said above and it could most likely be a bad ipr.

I would certainly bet money on the ICP sensor if it is an early 04 (03 style engine)
