The existing answer if very likely the most accurate however, NOx

is caused by excessive heat. Perhaps the fuel/air mixture is not to

spec. It also may be due to a fouled combustion chamber due to

carbon build-up. A fuel additive may be a simpler and less

expensive solution. Certainly worth the try.

You will want a good cleaning additive, however, you must be

careful because cleaning additives may also increase the heat and

make matters worse.

With any additive you should drive through a full tank of

treated fuel to get the best results.

I've read on the web about many such additives. STP, Techron and

the like. There is also one that seems to get good reports, at

least according to its website. It isn't widely available in

stores...again according to its website. I think it is called

BlueSky 3-in-1 Fuel Conditioner. Any one would probably do the

trick. good luck.
