emissions help
i have a 94 SE 1mz. i recently took her in for emissions testing and failed. i failed in hydrocarbons and NOx, but passed in CO and CO2. i failed thoes two only at low speeds and rpms, and durring acceleration when tested on the treadmill. the only modifications i have to the car is a cold air intake and a axle back with NO muffler (long story). are the failing numbers because of the low backpreasure caused by the lack of a muffler or is it somthiong else. any help would be great, thanks.
