Background: 95 Acccord EX Sedan (Auto) Running JDM H22A (Auto) w/ P0F ECU (SIR ECU) Injen Cold Air Intake DC Sports Header Magnaflow Catalytic Converter Custom 2.5 Exhaust w/ Vibrant Muffler VAFC-II (all settings at zero) (Note: This is my 2nd Engine. First one ran like shit and extremely lean then died) Emissions Problem: First Test: All numbers are good/Passed except for NOx which is almost double the limit. NOx 15mph @ 2137 (limit 1636) NOx 25mph @ 2289 (limit 1591) So went ahead and cleaned my EGR Ports and Valve which were clogged big time. Re-test: NOx 15mph @ 3111 (limit 1636) NOx 25mph @ 3533 (limit 1591) WTF? The numbers got worse? Any ideas or suggestions? I purchased the Magnaflow Cat a few years ago but could it have gotten bad from the first bad H22? I have no CEL lights after the EGR cleaning. I NEED HELP PLEASE. Getting ready to sell my car if I can't figure this out.
