2007 Jeep Commander Q&A
2007 Jeep Commander Question: Engine, transmission issue? Does not have much power and sounds loud.
Sounds like an exhaust flow issue. Check the flexpipe for leaks (between engine and catalytic converter) Possible that the cat. is failing and plugging causing backpressure to choke the engine under a load and may have ruptured the flexpipe (the weakest exhaust link). - csubak30
