2002 caravan problem

I have changed the oil,all filters,sparkplugs and wires but the problem is still there.At start up it vibrates and sputters,gets worse at take off,lessens at 55mph but if i floor the gas it stops.Takes alot more power to reach speeds.As much as 3000 rpm to get to 45 and almost 4000 rpm to get to 55mph.Any ideas on how i can fix this?

Sounds like one or more cylinders is not firing. Are you getting a check engine light and have you checked for codes?

No, the check engine light isnt on so i cant get a code. I wish it was that easy bud.

Don't we all. Here's one time when the old tried and true methods come into play. Have you verified all 6 are getting spark and fuel injectors are pulsing?

You may have pending codes waiting for that last of three detections that will fire the CE light.
