Trouble with Emission : HELP : 91 Civic Hatch
I am in Massachusetts, where the emission laws are damn tough (okay...not as
tough as CA....but tough enough!!). The car has 74K miles and it passed everything except the HC test (Higher hydrocarbon emissions - approx 25% higher than normal). The mechanic at the gas station who did the yearly inspection test told me that it needed a new air filter, new plugs and a PCV valve. I bought these parts and changed them over (even though the air filter & plugs were fairly new !!), excepting the PCV valve, as I don't have a deep socket 9/16" wrench (I'll get a socket for it tomorrow and try). I tried getting the PCV valve out with a 8" spanner wrench, but couldn't get the damn valve to come off (is it always this tight ?? anyone change one of these out ??). In any case, I am going to get a deep socket wrench and a longer driver and get the damn PCV valve out of there. I read in a Chilton Honda Civic service manual that says a mal-functioning PCV valve will make higher HC emissions. Right now I have "R" sticker on the inspection sticker area. The mechanic told me to change these things out (air filter, PCV valve & plugs) and come back and it should pass. Anyone think of anything else?? The inspection fee is $ 29 bucks in Mass, but on a R sticker is free for a first re-inspection. So, I want to be sure there is nothing more than this !! Thanks in advance for your response. Santino. |

Re: Trouble with Emission : HELP : 91 Civic Hatch
You might need a new a Catalytic converter. I had to replace mine after
134k miles. All the years before it passed easily under California emissions. Before replacing the CAT it read 600 over the max CO, after the new CAT was installed it was below the average.

Re: Trouble with Emission : HELP : 91 Civic Hatch
Joseph, Wilfred & Bill:
Thanks for your response. I think Bill may be right. Joseph my CO reading is normal. Here is the summary of Emissions: HC GPM Reading 1.80 Limit 1.20 Result : FAIL CO GPM Reading 14.58 Limit 20.00 Result : PASS NOx GPM Reading 0.87 Limit 2.50 Result : PASS I just finished changing the PCV valve ; there was a lot of carbon deposit, was black going into it. I had the oil changed just 1,000 miles ago. I could change it if you think it will make a difference...only $ 10 bucks. Please, you guys, if you think of anything else, please let me know. This Civic runs great otherwise, I can't afford to part with it. It is a good poor man's car (which is what I am...we eat hand to mouth !!). They are really difficult here in Mass with inspections. I have one more chance before I take it in for a final inspection. I will try to drive an hour before the inspection, hope that cleans it up ; but if there is anything else, I'd appreciate it if you let me know.
