The 2006 I have with the 4.0 I recently noticed has the converter rodded out. I’m assuming that the 2 others are still intact inside. The question that I have is, how important is the converter in the fuel mileage game? I have no codes and, no issues other than a kind of cough thing that the engine does occasionally. I’m thinking that it may have the incorrect spark plugs installed. I’ve already purchased the right ones.
This thing just gets ridiculously bad mileage. Like really bad. I don’t really want to spend money on a new system with all new converters but, I will if it’s all for the greater good.
