Hello.
I am hoping to get some ideas on what i might be able to do to help pass emissions.
I live in Vancouver, WA.
I have a 1988 5speed accord LX carberated.....200K miles on engine
Today I tried to pass emissions and failed the HC limit at idle. I DID pass the cruise limit.
ALSO- this car passed 2 years ago previously.
Earlier today the car was NOT starting. I replaced the rotor and rotor cap on the distributor and the car started up!
My next guess is to maybe try changing the spark plugs as well as a first, next attempt.
Anyway, here are my readings:
IDLE numbers:
HC = 1372, pass is 220
CO% = 0.16 (limit is 1.2 so this did pass)
CO + CO2 (%) = 7.96
O2% = 9.77
RPM = 1070
Cruise numbers:
HC = 106
CO% = 0.09
CO + CO2 (%) = 12.29
O2% = 3.86
Like I stated previously my first, cheap guess attempt would be to change the spark plugs. I pulled one spark plug previously and it was covered with DARK, BLACK soot.
This is frustrating because I think this is, ironically, the last emission test it will have to pass given that emissions at this time is not required for vehicles older then 25 years.
Is there any dope I can put in the gas to help get this baby to pass!
When I move some day, one of the requirements for new residence will be NO more emissions testing.
Hopefully I can get some ideas here on what I might want to attack. It seems like there is something funny going on here...perhaps a sensor or something?
Thanks in advance for any responses that might be provided on here and have a good day!
