Hi All, I have a 1993 Dodge Shadow 4 cyl 2.2L. The recent E-Check NOx emissions where 1220ppm which exceeded the allowable limit of 1026ppm. I realize I will have to take the car to an emissions specialist, but I was wondering if there were any obvious I could check first. The emission circuit hosing etc all seems ok. The car passed an emissions test a couple of years ago and seems to be running fine at the moment. Many thanks in advance for any helpful hints ... Cheers, Alan
