ECM & o2 sensor ?
Well, I'm wondering if my o2's are bad, I did have a SES light when I bought my truck, so I unplugged it and they never came back... Sometimes it smells like my truck is running rich, but tonight it smelled fine. Is there anyway to do the thing to make the computer flash ses light to show the code? IE. SES blink, blink...pause.... Blink.... Meaning 21. I know we did that with our tahoe. Also I went to buy a airfilter, FRAM... Well it was 16 bux! I had might as well spend alittle more and get a K&N or amsoil... think?
