Runs Rough no catalatic converter

Just bought 94 jeep cherokee lurado 5.2 4x4 It had been sitting out in sub 0 for 6 months. it starts but runs rough, I found it has had the catalitic converter removed, could this be the problem with the rattle when it shifts into higher gear, as when I press the overdrive button off the rough ride quits, it also emits plenty of exsaust. Thanks Dez.

    Thanks for the feedback, I was thinking the 02 sensors, hoping that would be the problem, I will throw a new caat in then let you know the outcome. Thanks Dez.

Well, i know that a took out a bad caat once and the truck ran terrible. So I went and put a new one in and it ran great. The O2 sensors can't read the exhaust gases correctly with out it. It was a Dodge with a 5.2L

My 1994 Jeep Grand Cherokee with the 5.2L is very difficult to start if it has not been run in the previous 6 hours. Replaced ignition coil but didn't solve the problem. After sitting overnight it


Low fuel pressure.
You need to check the fuel pressure on the first crank and watch it as it is running.
Requires a special gauge.
If it were just a starting problem I would say it could be a pump relay, but not if it runs rough for 5 min.
Might be a dirty filter or problem in the tank.

sounds like you either need a tune up,or the starter is going bad.It probably runs rough due to unburned gas from failed starts.

It sounds like a few different things or a combination of more than one.

  1. The EGR valve
  2. The catalytic converter
  3. The mass airflow sensor
