I have a b16a1 swap, and my car recently started burning WAY to much fuel...I thought it was the O2 sensor but the Computers not blinking and I have no check engine light. Gonna do a serious tune up soon though so hopefully it helps, cause about 10 miles to the gal is alittle crazy for a CRX! Also I'm gonna replace the O2 sensor, anyone know if I can just use a DOHC del sol O2, cause the stock JDM header had 2 sensors but the guys who did my swap chopped one off anywayz. Strange, I'd appreciate any ideas...Thanks!

 

Do you know what ECU you're using?

You'll need to use a stock CRX Si O2 sensor if it's a PR3/PW0 ECU.

 

I'm using the JDM sir ecu
