Nice job wrapping things up and letting us know about it.

Quote:

still occasionally throws that 15 code that crabtruck described - not sure why as the sensor is new

Remember that code can be tripped by the sensor or high resistance in circuit.
You live in a place where corrosion/oxidation is a factor, try cleaning the connector.
Make sure connector is not fatigued and loosening up.
Also be sure where sensor fits is clean for good electrical contact via threads.

Nice shiny rebuilt engine painted black. Duh - I did a poor job of cleaning a manifold stud & ended up with a bad (intermittant) ground. Probably makes the sensor look open to the ECM. All cleaned up now, no codes at all, purring & running better than ever.
