Failed CO Emissions BAD!!! UPDATED

[Totalimmortal]

My NOx was over twice what it should be and HC was very close. I do have a CEL for rear o2 even after replacing the sensor. So my car is pig rich from what I understand. After the test so far I've done and oil change, new spark plugs. I also have CEL for a CYP Low voltage. VTEC Solenoid(needs cleaned), and one other I dont remember. Im going to scan my paperwork in tomorrow so everyone can see my numbers, but for now some basic suggestions would be nice as this is my first time dealing with this.

This is for the Accord BTW

UPDATED IN LAST POST!

Check to see if there's oil leaking from the lower timing cover. You're probably going to have to replace the sensor(s) at the crank.

Post up the actual codes.

off topic, what year and number is the GVR4? My old track car was #300 from 1991.

The codes would help, and you should definitely replace the CYP sensor, I cant imagine the car running very well right now.

Car runs as well as it ever has, funny thing. Mine was a 91' and it was #981

Could be well off the beaten path here but..... have you cleaned out the EGR System at all since you've owned the car??

Re: Failed CO Emissions BAD!!!

IIRC i replaced the EGR valve about two years ago and cleaned all the ports. It couldnt hurt to do it again though......
