code 1226 knock sensor #2

[monty23psk]

you can test the sensors with a multimeter and measure the ohms... I dont have the specs, but if you search for my username, it should come up. if you cant find it, let me know and I will search it. One of mine has 0, but the car would run ok, just sometimes the hot start would cause the car to turn off.

Installed O2 sensor. No changes. Gonna replace knock sensors.

I had the same 1226 code and bad loss of power once warmed up.  A new o2 sensor fixed my problem.  

When was the last time your plugs were changed?  I wonder if a bad plug/wire may becausing a missfire affecting the knock sensor.

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.
