I got a new code after i got the header on, P0420, catalyst effieciency below threshold...so either the O2 sensors are bad or not tight enough?

http://www.club3g.com/forum/showthread.php?t=55284 if the sensor looks like the one the 3G eclipse uses then you can try that solution, otherwise theres actualy things called O2 simulators, search them online and you should find them or find out more about them, possibly how to make your own.
