'02 X66 is hesitating when coming out of the hole. Also when running at mid speeds. Will clear up some but does it quit often. Still get my rpm's. I've changed the plugs, fuel filter and put Sea Foam in the gas. Help!

On an '02 engine, I recommend cleaning the O2 sensor and rebuilding the fuel pump.
