AOS - Question

[SeanBuller]

Hi Guys,

We are currently trying out the procedure listed above. We swapped the upstream O2 sensors between bank 1 and bank 2 (bank 1 is misfiring). We cleared the codes for the vehicle and started it up. Still idling poorly and making the noise in the video above.

The CEL did not come on, but we are getting code P0012 which says "intake camshaft position timing -- over-retarded (bank 1)". Along with P0300, P0301, P0302, P0303. All relating to misfires of cylider 1-3 (Bank 1).

We have cleaned the MAF and now replacing all 6 spark plugs.

Is anyone familiar with these symptoms? Especially P0012.

Thanks!

Hey Sean; Before you reinstall those spark plugs, I'd recommend doing a compression test. If you do not have one there are loaners available from AutoZone, O'reilly's etc. Unfortunately it may be time to implement Markus' phase 2 plan. Hoping for the best!
