| What do not under stand is why is the NOx so much higher than two years ago? When basically nothing has changed. Unless the EGR vacuum line was unplugged.
I got exhaust soot on my finger when I manually pushed the Egr valve. SO some exhaust is getting though.
Does making it run richer it up help reduce the NOx ? The new Cat should help if I do richen it up to keep the CO down.
