SMOG pass?
hey guys i am trying to get my car to pass smog.I tried once and it failed don't want to do it again till i know forsure it will pass. i need help reading this scanner?i am getting a high knock sensor about 154 or higher sometimes is that normal and can it affect the emissions to fail smog?i cleaned out my EGR valve and check it with the vacuum see if the valve the diaphram is working ryte and it is.i know that my EGR is working fine it will reduces carbon build up>!My reading with the two oxygen sensor is sometimes abnormal left would be 385 and right would be 689 and sometimes it would be the other way around left side would be higher is that normal? 
pls help me give me some guide to check what sensors could be bad thats giving my PCM a bad reading maybe?Or give me any idea what to diagnos for it to pass smog.should i be getting some kind of a percent by the way with the EGR duty cycle coz im getting 0.0% and one time i had 99.4% when i was on the freeway,but everytime im at home car park but on im getting 0.0% on EGR cycle reading??
