Hey guys, I dunno how many of you have mandatory vehicle emissions testing in your region, but we have it here in BC, Canada - and my Pathy keeps failing!! It's ridiculous...
There's 3 parts to the test: CO2 emmision, NOX and Hydrocarbons I think.... I've passed 2 out of the 3 items everytime but it keeps failing on the NOX part.
It failed by 0.3 today - totally ticked me off.
Quick run down: I got a brand new cat, O2, air filter is clean, NGK platinum plugs, the truck idle's and runs absolutley perfect. EGR valve has been cleaned out, cap and rotor are a few months old as well as the fuel filter. I run it on 91 octane fuel. Truck had 274,000 kms.
I have no idea what to look at anymore! :furious:
Any ideas????????????????????????
