2007 Silverado Failed Smog Pulling codes P0121, P0175, P0300, P0430
I failed my California smog test because of these codes 121, 175, 300, 430. I have had the check engine light come on/off for the past 2 years. The vehicle runs great and there are no mechanical issues. If I fix one of the issues I can get a waiver for the other repairs and then have 2 years until my next smog to repair everything so that I will be able to pass my 2015 smog. Any suggestions on which issue to fix first so that I can get my smog waiver? <o
