So I have a 03 Durango 4.7 L and it has been hitting a rev limiter while in every gear. It gets to 3,500 RPMS and hits it. Plus, it will randomly shut off going down the road. Plus, it has an incredibly hard time taking off. It feels bogged down and the RPMS increase very slowly. Any ideas of the problem? I replaced my ECM module for a brand new one, pre-programmed to fit my specific Durango. Still having the issue though.
had the same thing happen a while back after changing a coil pack that was bad. Ended up being a bad connection in the harness going to the coil pack..
