I dont understand it,

I just recently replaced the Knock Sensor, for the reason of getting a code, and not to long ago (1 month) I replaced my dc header to the Ceramic version

at that time I replace my 02 sensor since I was already down their,

Now I get the code, but it doesnt come on when I have driven above 35 mph or past 4k rpm,

It throws the code as soon as the engine is started, no warmup or anything.

I am about to jack it up and put my multimeter on it and see what I read, but just wondering if anyone else has had the problem.


I did search the board, and saw the suggestion of Injectors as possible cause, but when I pull my plugs they look good, so I can only think that since I do not visually see a lean or rich condition on the plugs that the injector(s) are not faulty

one more thing, IF the O2 sensor is faulty, would I be feeling the same symptoms as if my knock sensor was bad.... as of right now I am not,

so I confused

Pull the CEL code! See what it is, before you throw parts at it!

I did,

got code #1 (o2 Sensor)

Thats why I am lost it is not that old(o2 Sensor), but I took a multimeter to the harness of the 02 sensor and I am getting above .1v of current from ecu, I have my ground, and read power for the heat wires.


I just went to local store and picked up a new o2 sensor and see what happens, just rather odd I think



* I also double checked my injectors and I am reading 1.0 ~ 2.5 ohms on them, so I dont think anything is wrong with those.
