I have an '04 6.0 with 127,000, about a week ago i noticed it was taking longer than normal to accelerate when i put the pedal to the floor. Saturday it was having a real hard time, and acted like it was being starved for fuel so I replaced the fuel filters, I got my low end power back but still have nothing on the top end
If i depress the pedal to about 1/4 to 1/2 way down, the truck accelerates just fine and gains speed. If I punch it to the floor, the truck will shift, rev up to 3k and gain speed very very slowly (i'd say about 2-3 mph per second where as it used to put you back in the seat when you'd punch it), but if i start easing off the pedal the truck will shift again and take off.
do you guys think I lost a gear or I've got a band that is just severely stretched or there is something else wrong with the truck
(also all gauges read fine and I've got no lights on the dash)
