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.

 

anyone?....

 

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?

 

HC are hydrocarbons.. or unburned fuel.. sounds like your car is running a little rich

 

thanks guys...im gonna get it checked out on the weekend..all ur help was appreciated

 

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?

 

man it's been song long since i've used a 5 gas

 

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...

maybe its time for a tune-up

 

seafoam it... it gets rid of all the carbon build up in the motor... and do a tune up... how miles is on it?

 

the car has about 200kms on it. Seafoam? whats that? Can you give me a link to were I can read about it. Yes a Tune up will be done this weekend and I may change the spark plugs... Thanks for all the information I really appreciate it!

 

just put "seafoam" in the search function... there r alot of DIY on sea foam... just do research before u do it... 200k motor is almost to the end of the line... my buddy pushed his almost to 300k lol

 

seafoam is not gonna help in this case because all the numbers are low, what you need to do is get a tune up and change the spark plugs
