Ok guys, please help a damsell in distress... Got a 93 Civic Cx (5 spd hatchback), tried twice to e-test it, but failed. Both times all the other readings were amazing, but Nox failed miserably (do I really need to find the papers and give you the exact numbers?) First time didn't do anything, and Nox were double the allowed, so I got a new (3-way) cat put in, booked another test, run it for an hour to make sure she was all warm and fuzzy and went in... this time Nox 4 times the allowed!!! What's going on???! I know, your'e going to suggest a faulty EGR valve, but my car doesn't have one. So... maybe it be the rad? It's pretty raggedy...Or thermostat? (Still original) Anything else? It's got almost 260k on it, and the oil has been changed every 5k, the engine is clean as a whistle. It has a stainless steel exhaust and a custom made muffler, but those shouldn't make a difference, should they? Maybe my timing is off? Would there be any symptoms? I'd really appreciate any advice; I hate it when they try to screw me over just because I wear a skirt!
