I just came up with this crazy idea..... my car keeps failing NOx which is caused by running to lean. (too much air, too little fuel). If i cover the airfilter slightly with a plastic bag, restricting the amount of air going into the engine. thus making the car run richer. and hopefully reduce the NOx reading. What do u guys think? will it work? what are the dangers?
