I've had my emissions checked twice and failed both times. The problem is the NOx.
The limit is 1313 ppm and the first time I was at 1688.4 ppm. So I looked on here for things to check to fix this. I made sure the EGR valve is working and made sure the timing is right. I also made sure all the spark plugs are looking good. Also made sure the PCV valve is good. A lot of people I ask about this say it's my catalytic convertor, however, it is only a year or so old.
I went and had it checked again today and after I checked that stuff, the NOx went up. Now it is reading 1840 ppm. This is really pissing me off. What else can I check?
