I've had the Megan tp with this setup for 5000 miles and no issues whatsoever. It just works.

 

Search "cel fix", "o2 simulator" that will def help you out! =)

 

you probably didn't insert a spacer in to the bung where the o2 sensor plugs in

 

yea read that thread or go to ebay and search o2 simiulater and it will show up one for lilke 2.99
