    Not a wear ring cavitation issue it pulls out of the hole fine .
    Engine don't pick up revs at all for 3 sec then slow climb for 2 sec then flat out
    So no rpm to cavitate.
    I'm thinking the little water that got through the air filter has maybe got on something else like icv or tps or injectors ? I don't know looking for advice really .

    First thing I would do is drop another new set of plugs in it.

    I'm thinking would to much oil cause this?
