2003 Ram 1500
4.7L 190,000 miles just replaced all coil packs, fuel pump and TPS.... runs pretty good but it doesn't fel like it has it's full "balls". i noticed this when accelerating to highway speed....it reached 70 and I let off the pedal to maintain speed. when my speed decreased a little, I depressed the pedal slightly to rergain speed and the engine had a "shudder" as if not firing on all cylinders. I pressed the pedal harder to hit passing gear and it regains "strength" but when the transmission hits OD and the RPMs drop it loses its "balls" and has a sluggish feel. Now, just city driving...no issues. This seems to be something that occurs during highway conditions.
JA: Have you ever replaced the fuel pump, or is this the original?
Customer: New fuel pump
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Are you reading my posts?
JA: No. I'm the Dodge Mechanic's Assistant.
Customer: read the post...it clearly states what I have done and what is occurring.
JA: Anything else you think the mechanic should know?
Customer: That's all that I can think of....perhaps he will have an idea and ask but I think I've given a clear picture of my problem, thank you.
