Well my 92 Renegade failed PA state emissions test today 190 K 4.0L 5spd.
Co 2.04% Limit 5.40% Passed
HC 324 ppm Limit 537 Passed
NO 8048ppm Limit 7380 Failed
This test is run on a dyno with the engine warm and the vehicle under 50% load. I think a new Cat. will fix the problem but don't want to spend the money if I don't have too I mean its only failing by 668 Parts per million for NO. Anyone have any ideas and do any of the Emission Test passers in a jar work?
