2004 Mazda 3.0 tribute lean bank 2, secondary ignition
Looking for some more guidance, previous history is valve covers, timing cover and oil pan gaskets where replaced as well as spark plugs and #5 coil pack. When I got it there is codes for bank 2 lean condition I did a cylinder drop #4 and #6 are not contributeing at all, the secondary ignition wave form is where it gets weird for me all of bank 1 is showing higher KV around 12-15 then bank 2 shows 4-7kv. I am leaning towards a compression or timing issue since that cover was off as well as low KV can be related to timing or compression problem any guidance would be helpful.
