2003 3.0 part throttle stumble
When at operating temp engine stumbles momentarily at part throttle.
It's like a buck more than a misfire, no check engine light either.
I have 120,000+ miles on truck, only repairs ever needed so far was the camshaft synchro and sensor (Motorcraft parts) about 2 years ago, oh and the brake pads were replaced at about 110,000 miles (the original ones!).
My symptoms are very similiar to folks who have faulty DPFE, but I have
learned my year of vulcan does not have one.
Any ideas? Truck runs ok otherwise.
