swap help!
 

I cannot find anything on the problems i am having. I pulled out the f23a ulev motor out of a 2002 lx coupe. The check engine light is on for a 02 sensor that was replaced last year that should still be good.but should i try another 02 sensor. And the temperature gauge does not work any suggestions?

Would running a h22 ecu fix my head ache

What did you put the 02 motor into?

Sorry the f23 ulev came out and i put in an f20b

Do you remember if the valve cover had "green" writing on is saying sulv....or something like that.

I'm trying to back into a few things.....the sulv had an a/f type O2 vs a "normal" O2. Also, the 02 temp gauge was driven by the ECT via the ECU - does the F20 have the single pin temp sender?
