Enrique changed the oil & got the AC super cold.
I guess he'll be seeing me again real soon.

I'm not sure where to start & hope Enrique can figure it out.

Hi Guys, I'm back!


2009 Failed Smog



Passed 2009 Smog after new O2 senser (NO levele went down)

So hoping a new O2 will work but do they only last 1200 miles?

2009 Pass Smog:



History:
O2 sensor was changed in 2009 with 1200 m ileage.
New SP wires Dist cap & rotor (1500 miles). New fuel acummulator 2008
Air Filter has 1500 miles

2011 Smog Pass



Only 700 miles in last 2 years since 2011 smog pass

2013 Smog Fail



She's basically failing on the NO
Max 15mph is 1074 mease 1532
Max 25mph is 904 meas 1372

& tad high 20 points over max on HC in the 15mph

Could be a vacumn leak?
EGR valve?

I ran it 30 miles before taking it in so it should have been at operating temp.



Anyone have any advise?

She passed fine 2 years ago & there have been no engine adjustments



Thanks
