Failed Emission Test need help...
ok so I went to do the emission test and everything was good except for this:
HC ppm: LIMIT=82 READING 128 = FAIL
The READING is what I got on the test. So what is the problem? I dont get what HC ppm stands for. Im a newb when it comes to engine stuff like this so can anyone help me out? Thanks in advance
EDIT: forgot the mention the car is a 1993 Honda civic VX Hatchback with the stock engine.

Re: Failed Emission Test need help... (Evolution Type R)
how many miles on your engine?
Did you change spark plugs, wires, dizzy cap n rotor, fuel filter... etc. etc.?
basic tune up parts.
Catalytic converter ok?

Re: Failed Emission Test need help... (geebs)
its not running rich per se, if it was you would have a high CO, HC is unburned fuel...usually comes from the ignition side, does the car misfire?

CO% Limit=0.45 READING=0.00
NO ppm Limit= 636 READING=287
those numbers sound good to me. It does not misfire. Just when I stall the engine its like if it backfiring... Thanks for the help!
EDIT: the car idles at 745rpm can this also be the problem?
also the car failed on the ASM2525 TEST but passed on the Curb Idle test...
