Engine runs rough and barely has power

Asked by Chance Jan 03, 2021 at 09:30 AM about the 2004 Jeep Grand Cherokee Laredo 4WD

Question type: Maintenance & Repair

I've replaced around 5 or 6 hundred dollars worth of parts.
Fuel injectors all kinds of sensors and still runs rough
barely has any power and when it does run it won't go past
50mph... Only thing left is o2 sensors and entire exhaust
system. Am I on the right path and any other suggestions
plz.

The basics for problems at higher rpms, check for blockage of some kind. The first two things I think of are fuel and exhaust. Have you used a gage and checked proper fuel pressure? I agree with the other post about checking for trouble codes.
