I'm going for intake/exhaust leak this will effect O2 readings but doesn't mean O2 sensor is shot it just means poor reading from sensor due to leak

I found the leak. I huge hole the size of a pencil under an elbow towards the back of the engine area. A short black rubber elbow off the back of the intake manifold.

 

 

Ok I taped the hole till I get a new hose. Reset and drove 20 miles, all obd2 tests ran, and no check engine light.

 

audiforums helps once again!

 

when it says "hose leak" this is the sort of thing it means
