So I took it to get it smogged the first time and it passed smog with perfect numbers, all I needed to do was put a pcv grommet on and adjust the timing to 14, for him to pass it, so I did that. Then I took it back the second time and it didn't pass at IDLE. Does anyone know what the problem could be?
Here are the numbers at idle.


RPM-935

CO2-MEAS-8.70

02-MEAS-2.60

HC-MAX-120-AVE-29-MEAS-155

CO-MAX-1.00-AVE-0.10-MEAS-0.19

 

Did you drive a short distance to the place? Its recommend that you drive 20 min on the highway to clean out the system.

 

Yeah i drove around town and on the highway, it was hot.

 

Recheck your timing

 

Any recent tune-up?
What was done?

To me it looks like maybe a lazy O2.

 

I replaced the cap, rotor and plugs before the smog test. And i just checked the timing again and its at 14. I'm thinking about getting some seafoam to clean out all the carbons..

 

Seafoam works wonders worth the try

 

Woops... read that wrong.
Thought you had high Co and HC. (C02 messed me up somehow)

HC caused by ignition problems - typically too advanced (did you make sure to short the service connector when you checked/set timing?)
Old and worn components are also culprits - all that would be left are your wires.
Burnt valves also cause high HC.
Leaky

Do a compression check.
Low compression will do you in.
