My check engine light is on and I was told I needed to replace the Oxygen sensor. The car idels rough and miss fires. I'm not sure which sensor I needed to Buy Upstream or downstream.

Oxygen sensors need to be replaced every 75-100,000 miles depending upon you vehicle make.

You did not say if you have a hydrogen generator installed, and if you do, have you installed a MAP Sensor Enhancer?

As far as your EFIE, you have 1 narrow band upstream of your catalytic converter so one of our single narrow band EFIE?s is what would work.

The ?Quad Digital EFIE? in these cases because it has the superior digital circuitry and it?s the most flexible if ever used on another vehicle.

Please email with any other questions.
Thanks
