i have a 1994 honda accord. continues to fail ASM emmission test. HC ppm = 1800 allowed 127, NOx 1600 allowed 910. replaced the catalytic coverter (results were reduced to 300 NOx ppm, HC remained 1800. Replace the oxygen sensor HC ppm = 2000, NOx=1600 both failed, Timing is good, No vacuum leaks, Plugs have been replace. How can I reduce readings to within allowable limits?

I posted my question is here on Edmunds Answers. Same title. Brief Summary: Larger cooling fan not working. Replaced motor($48), sender($32) & sensor($12), and checked fuse by switching wtih power windows. Windows still worked. Still no action from larger fan(the right looking into car. Left from drivers seat) while smaller A/C fan is still working. Need Ideas, a part name, or repair place. Local mechanic recommend sensor and sender change. When hot wired to the battery, larger fan worked perfectly... but I cant leave it like that! I asked at Autoparts Advance. He recommended a Temperature Switch change($44). Car gets to 3 quaters hot but thats as high as it will go as running my A/C provides some cooling as smaller a/C fan still runs. Not the Thermostat as when it says the car is getting hot, it starts to act sluggish and the interior begins to feel hot. Only noticed at red lights. While moving(25+mph not and directly behind someone like traffic), mother nature cools the car down to normal operating temperature. Currently Carpooling and Driving Dad's Expedition (OMG IT CAN BURN $80 IN GAS IN NO TIME!!) and can't wait to be back in my own seat and to stop paying $80 in gas...

Can anyone point me in the direction of a good Honda mechanic in the Annapolis, MD area. I have a '95 Accord EX with 185,440 miles and it didn't pass the emissions test! HC was .7436 that passed. CO was 9.7428 that passed. My problem is the NOx it was 3.7803 and it should not be over 2.1000. I also have a few other problems that I would like to have fixed. I love my baby and have been driving her for the last 12 years. I bought her brand new and have taken good care of her. She's just getting a little old and I need someone who can help me take care of her!

Replying to: yankeey2g (Oct 21, 2007 7:25 am) I wrote this post about poor mpg when I first got my accord. The mpg was so bad that I was even thinking about getting rid of the car. Well I’m glad I didn’t. It seems that city driving is terrible on my car. I get about 200-15 per 13-14 gallon tank. The car performs completely different on long hauls. I took a 250 miles trip today and only used half a tank of gas (I filled up on ‘regular’ from Mobil). I was cruising between 60-75 mph most of the time. I haven’t done much work on the car. I did a tune up (plugs, wires, fuel filter) and added a can of valvoline Fuel Injector cleaner about 2 months ago. Do you think the mpg will increase by adding a cold air intake? The muffler is also shot dead - the join to the exhaust pipes is rotten and pretty much broken off. Thanks for your help!
