97dxSleeper

I have a 97 dx with a 2000 ex swap and I am going through a full tank of gas in two days. My check engine light is on. And it comes up as both of my o2 sensors are bad. Could that be the reason why? Thank you for looking.

yes thats your problem right there may not hurt to do a fuel filter air filter cap roter and plugs and wires


but yes get those 2 o2 sensors fixed

any other codes at all as well?

There was one other one the one that goes on your cold air intake but I fixed that. Thanks man I'm new to the honda game

if you do the work yourself I would recommend desno O2 sensors kinda pricy like 35+
I bought a cheap one 12$ that lasted a month and had to do the work 2x

or pay someone there "fun" to remove and the amount the shop charged me was worth the not having the aggravation

I had them priced out at AutoZone and they were like 60 dollars each. Facckkk

The primary O2 sensor is the one you need to replace - the secondary is just there to see if the cat is doing its job.

I don't have a cat on it.
