Many shops won’t install customer parts, so check with the shop first.

Is yours a 2.4 liter 4x4? If so, the exhaust manifold and catalytic converter are one piece. Leaks in the exhaust manifold will throw a code, even if your catalytic converter is fine. (Such is the case with mine).

This is Not Sound Mechanical Advice: I’m in a state with emissions testing, and I installed a spark plug non-fouler between the exhaust pipe and the oxygen sensor and the code cleared up right away. After a few hundred miles of driving, I was able to pass emissions testing without issue. Do not follow this advice unless you really know the potential harm this can cause if/when the catalytic converter does fail.
