Ok so im on the highway and i have very little power until about 3000RPM. It cant even maintain 100km/h unless im at like 2800rpm and even then it struggles. My XJ is an '89 4door with a 4.0L auto. my air filter is new and clean. i have proffesionaly purged my fuel system including changing the filter. my exhaust is simply straight pipe to a bottle. no catylitic converter or muffler. My jeep has been outfitted with 31x10.50's for over a year but the problem with power is recent. what am i missing why does it feel like it does nothing untill 3000rpm? im losing my mind.
