Lean on idle, rich on cruising
 

hey guys

i was just checking my emissions and they seem to be kinda high
on idle the car goes lean and goes rich while cruising
i got the high flow cat, air pump installed

the guy who checked my emissions said that probably is some sort of a sensor but since hes not a rotary expert he doesnt know

i changed my o2 sensor in august 2006 and only coverred 7000kms since then

where else should i be looking?



Thank you

What are your AFR's?

as i saw in the machine which u have to use a formula to get the AFR (i dont know it) on idle it was 0.89 and on 3k revs 1.15 approx ..or the vise versa...

That's not AFR that is emissions.

Emissions I wouldn't worry about as long as it is legal to drive it around and if you follow advice for mods.

even though is not accurate but just to get an idea..i got the apexi turbo timer which reads my AFR and varies between 16-20
i know its cheap shit and no accurate..

the apexi turbo timer does not show accurate AFR's I know I have one and its way off.
