make sure you have an O2 sensor hooked up, and make sure *it works*.

how about adjusting the co_pot or retarding timing? are you trying to pass emissions?

get a AF gauge off bilal. i have one in my car. same as the yanks use too (G60 peeps anyway)

 

itll show signs of the o2 probe working properly.

 

as a rough indication i run without cat n i believe when they did the job the killed the probe(then didn't plug it back in)

 

has seemed lean since so last wek i did a test. was 0.7% at idle with probe. unplugged around the 3% mark
