i got the car with a new exast all crome.. thing is it didnt have an oxy sencer..4 wire there 4 dif colors . the connecor is gone so how do i con. the new one what wire goes where.. it must matter the car wont run once its warm.. well it runs but sounds and acts like its running on 3 cyl.. im stumped and need it going bad

 

so when you got the car there was no sensor or sensor wiring at all?

Is there even a connector the sensor plugs in to left?

 

You say it doesn't run right - does that mean you randomly hooked up the 4 wires & tried it? If you crossed the sensor heater ground to the wrong wire of the ECU, you may have done some damage... What exactly did you do??

 

Return it and get a OEM NTK O2 sensor. Bosch and other "Aftermarket" O2 sensors don't run correctly with Hondas.

I got bad O2 sensor and Fuel supply issue CELs shortly after installing a Bosch O2 sensor. Car bogged bad and ran with low power. Replaced with NTK O2 sensor and car ran great. No CELs!

Hope this helps.

Cheapest place I found. Worked perfectly. Was even cheaper than the Bosch from Autozone.
