Hi folks, The Civic will not pass inspection in New York, engine light is not on. The following codes show "Not Ready" O2(#1), CATALYS, O2(#2), EVAC. (I know I need to drive the car after replacing emmision parts) Replaced the following with Honda parts: the top(#1) O2 sensor($140) and the bottom(#2) O2 sensor ($250)... The (#1) top O2 comes up ready now, but the bottom (#2) O2 sensor still Not ready.. I changed the thermostat for kicks but that didn?t help.. Not sure why it?s saying EVAC not ready, when you loosen the gas cap you hear a vacum sound. We put over 500 miles on thing too.. The owner of the inspection garage called the state and they suggested the following: (this is nuts, but we tried it) 1. Let the car sit for 8 hours start it and hold at
3000rpm until the cooling fan come on and drive it 50 to 60 mph for 5 minutes then stop for 5 seconds and repeat 3 times. 2. With a 1/2 to 3/4 tank of gas drive 65 mph for 5 minutes, stop remove the gas cap and let it idle for 5 minutes and replace cap, then repeat 3 times. The 3rd option I don?t remember off hand but it was similiar to the others. Any suggestions whithout replacing the Cat?- posted
