OXYGEN sensor. just check it out make sure there are no problems with it like wiring or the sensor just might be shity ----

thats what i thought too. so i replaced the oxygen sensor. i was wondering if there was a leak right after the o2 would it cause the sensor to go on and off like i am experiencing.

Incorrectly wired, or some wierd issue.

Is the ECU chipped?

Does the car stumble at a highway cruise?

Anything else you can think of?

I have a diagram in my head, and my mspaint skills suck. If you start describing the system as you have it configured I can be of help.

PS - DIY rule of thumb? If YOU wired the sensor according to vowel shifting surrender monkey specifications and then you get a code for said sensor, it's probably not the sensor that's bad.

alright the oe color on the o2 are 2 black 1 green 1 white. the universal is 2 black 1 white 1 blue.
i wired it black to black white to white and blue to green.


the code 1 when alway for a while today and then came back on again with a code 43 after i messed with the fpr.
would a obd0 computer have anything to do with this, cause i have a 93 civic with an ls.
