so i went to get my 7 inspected the other day she did great up to the snilffer test... first the guy was having problems getting a good reading then i had to adjust my idle... my car was idling (on my tach) at like 350- 400 and it said 1100!!! on his computer..WTF? i leaned her way out and i still blew 1230HC. i have done everything to get her to pass.. new plugs, wires, air filter, fuel filter, oil change.... i guessing if he could get a better reading then maybe she would possibly pass or come closer...

 

the lady who owned her befor me replaced the cat...

 

You should try some of that 'Guarenteed to Pass' stuff that you can buy at your local parts store. I would also think that adjusting the idle down wouldn't really have an effect on the mixture, there's a separate screw for that.

 

Looked at your ACV yet? Are the lines to the cat connected? You should be able to pass emissions testing - sniffer - with a reasonably tuned vehicle (plugs, cap, rotor, etc), good cat and a working ACV system.

 

i also adjusted the mixture screw and leaned it way out. i had to get my idle down for his comp to register that my car was idling right im not too sure why my tach said 350-400 rpms when his read 1100..(as my car barely stayed at idle, and almost died).. i heard he might have been clamping the wrong wire ? i dont know im going to geat that pass emissions crap and drive the crap out of her befor i bring it back in.
