I have a 94 cx, original motor is completely stock. I failed emissions (CO was 12.46 and should be under 12.00) so im going to replace my fuel filter and PCV valve.
The thing is, I dont know anything about motors, I'm learning. Can someone explain maybe a simple walk through on changing a pcv valve... its under my fuel rail right?

Any other pointers to lower my CO level would be appreciated!
