[QUOTE="IndyDoF, post: 442441, member: 22413"] I purchased my 2013 JK Auto in March 2019 and have been getting misfiring codes on Bank 1 (most misfiring is happening on Cylinder 3) since I bought it. Things i have tried: [LIST] [*]Camshaft position sensor [*]New ECU [*]Bank 2 wiring loom (fixing another issue) [*]Checked wiring loom [*]6 x new coils [*]6 x new spark plugs [*]New lower manifold and seals [/LIST] Next on my list: [LIST] [*]Catalytic Converter (getting code for this now, probably related to misfire) [*]O2 sensors [*]Injector clean [*]PCV valve [/LIST] Valve cover is off at the moment while i wait for new valve cover gaskets but rockers look all good. I originally suspected electrical issue but now im not so sure. Any other ideas? [/QUOTE]
