Anyone here have experience with getting their catalytic converter replaced under the emmisions warranty with BMW? I had several fuel injectors go bad a couple of months ago which caused some major misfires. My indy replaced the injectors and everything runs great except he had warned me that the catalytic converter may have been impacted due to excess fuel getting into it. He suggested I give it a couple of thousand miles of driving to see if it would clear itself up but it hasn't. I keep getting the check engine light with the code "catalyst efficiency below threshold".

I wouldn't mention to the dealer having the injectors replaced, it being done by an indy', or you driving the car with misfires.
