Now two years later everything else in the test was exactly the same but the NOx levels are now above the max level around 750. What could be the problem?
I have heard the things to do is replace the air cleaner, get some of that guarntee to pass gas additive etc. I have replace the plugs and new wires. It uses a magneto so there is no distributor to mess with.
Not sure about NOx sensors.
Any help would be greatly appreciated.
have the same problem?
