OmG i cant believe my car failed the emissions test today for the 8th time Idk what is wrong with my car, its completely stock and its a 1990 civic with the stock engine and stock ecu. It doesnt even have an intake, and there is no CEL on. I just had the oil changed on it, and an extensive tune up done with full coolant service too. It didnt overheat on the machine. Anyways, heres the results.
25/25 Test Reading----------Allowed
HC ppm----999--------------147 Fail
CO %------100.0-------------0.82 Fail
NOx ppm---8000------------1072 Fail
RPM--------750------------3000 Max

50/15 Test Reading---------Allowed

Oh yeah, did i forget to mention the car also has a test pipe on it? I thought it was supposed to increese exhaust phlow to add horsepowahhh and give a better emissions reading.
