Ok so i just got my car certified and insured so now I need to pass the emmisions test. Stupidly I took the car from my uncles garage (where it had been sitting for about nine months) straight to the E-test centre. It failed horribly, in every category and after realizing how dumb that was i'm kicking myself for watin gthe $35 on the test before doing anything to clean it up. Results: RPM: 2084 Dilution (?) 15.5 valid HC ppm- limit: 75 result: 225 CO%- limit 0.42 result: 3.31 NOx- limit: 576 result: 1444 RPM: 1025 Dilution (?) 16.7 valid HC ppm- limit: 200 result: 393 CO%- limit: 1.00 result: 6.21 NOx- N/A This is my first car, and i'm a noober. What i've done so far to help clean out the engine and emissions system was I put a full tank of premium fuel in and added a bottle of this 'guarunteed to pass' stuff that is supposed to make your car pass or you get your money back (i've heard from some people it helps and some say it does nothing) If at all possible i'm trying to save as much money as i can to pass, having just put a new clutch/alternator/valves in the damn car. Any help is appreciated, thanks.
