Hey guys, after rebuilding the transmission in my 2008 JKU a few weeks ago, the CEL came on this past weekend with P0430, bank 2. I've been hearing a strange engine noise for weeks (well before the transmission issues) and I've thought about removing the driver-side heat shield to inspect the exhaust manifold. I'm not sure how to describe the noise.
When the transmission shop pulled the codes before rebuilding the transmission, they mentioned a catalytic converter code (but didn't tell me which one) which makes me wonder about water damage. We've driven the Jeep for two weeks without any codes, then took a trip up to Gatlinburg and the CEL came on with P0430. How would you recommend troubleshooting this? Should I test the O2 sensor first?
Thanks.
