So I finally received my code reader today. I have a few stored codes, but I know why they are there. When I run the K.O.E.O. test, I get the 111, so I think Im good there. (I read that was the "all clear" code) When I run the K.O.E.R. test I get a 311 which stands for, "Thermactor air system fault during engine run self test." I also get a 314, which is the same, but has "left side" on the end... Is this a fancy way of saying I have a vacuum leak? I removed my smog pump, and just plugged the vacuum lines that ran to it. My CEL never came on after that project. It just started after the intake swap... My CEL comes on mostly when the engine is under more of a load, such as going up a long hill, or cruising at low RPMs such as 1500-2000. Ill start here and see what you guys think if you dont mind helpin a rookie... If you have questions to help the investigation, please ask away.
