Hi All,
I have an 81 GTV6 that didn't pass smog here in Kalifornia. It was too high in HC on the low speed part of the test.
I was told my timing was off by 2 degrees (but that didn't fail it as Kali says +/-3 degrees is OK). So now that I have a timing light, how do I time it? I'm guessing I should disconnect the vac line.. but then what line should it line up with? It appears the timing is about 5mm right of the "F".
Also, how do you adjust the idle? Mine seems a little low. I was told the 20mm threaded deal on my throttle body is the idle adjustment, and there is a set nut, and a washer in there. I took it apart, verified the washer wasn't cracked or missing. But tightening or loosening the fitting didn't seem to affect my idle speed.
Any ideas?
Thanks.
