- Changed up/down stream 02 sensors on bank 2 because CEL said bank 2 sensor 1 had an issue
- after replacing sensors, car shows misfire in cylinder 2, and codes P0356 P0352
- check wires and connections can't find any issues/ buy 2 ignition coils to replace 6th and 2nd coils
-CEL lights and codes P0356 P0352 still showing
-have not checked the spark plugs
Looking for any other advice on where to look. Also, I noticed it looks like there is a lot of oil leaking toward the back of the engine, specifically where the intake manifold gaskets are. Really need to clear these CEL because car is running shitty and Service Stabilitrak notification is showing.
