02' throttle "feathering" while cruising....
Hi Folks!
I just had an exhaust manifold replaced on my F-150. It has the small 8 cyl..
While the manifold was leaking, the truck of course ran like crap.....spitting, sputtering, barfing, etc.
Now that the manifold work has been done, the truck runs pretty well, except for some intermittent increase in throttle (not by me) when cruising at highway speeds. This is comperable to the "feathering" of the throttle that you would do when checking for engine noises.
Hard to explain without feeling dopey, but kind of a mild ruuum, ruuum, ruuum out of nowhere when I'm cruising along.
I drive a 5 hr. trip every weekend, and it will do this about every 10-20 minutes.
I hope this makes SOME sense.
Any suggestions of course, will be greatly appreciated!
THANX!

This occurs regardless of the geography.....level or hilly.
Yup, it was the passenger side manifold.
Don't have cruise control or tach. You can definitely feel the truck surge with the engine rpm increase. even though each rev lasts about a second and they come is bursts of 4 to 8.

yeah mine does it about the same. cruise set at 65 and all of a sudden seems like it wants to take off. then it stops. it will do it to me as well if i am sitting in the driveway and rev the truck to 2500 rpms, hold it steady, then itll rev about 300 rpms and then drop back to 2500.
