Problem still exists. I have a nasty choppy/sounds like I have big cams idle, yet my tach needle stays steady right where it should. I was getting the 1226 code, then I replaced the O2 sensor and the code dissapeared but then 1222 popped up. Today I replaced both of my knock sensors, cleaned my IACV, and replaced my plugs and wires. Started car up and it still runs the same, but now the 1226 knock sensor 2 code is back. I dont know what the deal is. How can I clear the damn codes? Ive had the negative cable off for hours, and I heard when pulling codes if you hold the pedal down for 10 seconds the CEL will go off and it will clear, but I did this and it doesnt work.
Also when pulling codes will it only show 1 code or what? Mine will flash the same 1226 code over and over again, at least 10 times in a row, I get fed up and just turn it off instead of seeing if it will stop.
