My younger son is in the Army out of state. He has a 2005 Jeep Wrangler with 4.0L and 6-speed. He has about 106K miles on it, and just experienced catalytic converters failing / getting clogged, which caused it to run rough / poorly. The rear one right off the engine was glowing orange. The whole time, no CEL on the instrument panel. Anyway, my son replaced the plugs and a muffler shop replaced the exhaust from engine to muffler outlet with parts my son supplied.
He called me on the way back to the base and said it is still running like crap. He has over 3/4 tank of gas; I suggested some condensation since they have had some recent cooler temps, but he insists its running like it was before the exhaust replacement. Still no CEL.
Any thoughts? I hate that he is too far away for me to drive over and help.
