Well last night I put back in the old 02 and the old speed sensor and the test ran fine. I screwed it up at the end and hit enter before I turned the engine off but it ran. My questions is how in the world can an 02 sensor cause the Evap test to kick a P0502. I am going to rerun this weekend and hopefully get everything to pass.
