My 1995 Civic EX 1.6L failed the idle HC emmsions test. I have replace the O2 sensor, catalytic converter, distributer cap, rotor, wires, plugs and had an oil change. I was told it could possibly be the PCV valve or EGR Valve. My local Honda dealer could not find the EGR valve for my year and another Honda dealer said my year does not even have one. Any ideas on this, could it be called something else? Also, any ideas on the failed emmsions would be greatly appreciated.

Thanks

 

Make sure the iginition timing is dead on. If the timing is advanced, the HC emissions go up.

Other possibilities are;
vacuum leaks
ignition missfires
Cat conv. not warmed up
dirty, clogged injectors
bad gas

EGR system has nothing to do with HC, only Nox.

 

Thanks, After looking around some more i notice a small tear in the hose that comes off the head and goes to the pcv valve and air intake housing. Some oil looking fluid has leaked out, I wiped it down and after driving around checked again and more had leaked out. Possibility?

 

I find this thread completely amazing,, you have spent a bunch of money just replacing parts, On your own I have to assume ??In an attempt to correct the problem..Its time to call it quits..If you want to get your corrected,, its time to bring it to a qualified repair facility, this might be a very good Independant or a dealer.They should be able to tell you the problem within 1 hours labor time, do what the recommend and then have THEM perform the inspection. If it fails again, that means they were wrong and you dont have to pay for that repair. They will try again,, hopefully, you will get your car to pass for a lot less money then you already have thrown at it, trying to fix it your self or asking people on here for advise, when we cant see the the actual results of the test equiptment ???

 

Since you know nothing about who i have taken it to if you can't or don't want to help please say nothing. This thread is no more amazing than any of the other ones from people with questions.

 

KrzyCivic,,When you post a message for help on this forum, you open your self to anyone.. Otherwise, you might add to your post, "only this person or maybe that person can respond" I was only trying to help you resolve your problem.. You obvoiusly have been attempting to correct your problem with the wrong advise,, otherwise your wouldnt have replaced all those items already. I was attempting to steer you in the correct path to get your car fixed correctly, the first time.. Believe me when I tell you that i could tell you exactly what was wrong with your car within 1 Hour.. IF it didnt fix it, I wont charge you for parts or labor, further diagnostic time and would then cost you nothing.. Until I fix your car.. Ive been a Honda technician for the past 24 years,,I have seen problems just like yours for that many years. Ive been a Shop Forman for the past 12 years, meaning I have to know all the answers for every car that comes into the Shop.. When I said that i found your post "amazing" I wasnt thinking what you posted was wrong? What I thought was "amazing" was the fact that you have been steered in the wrong direction so many times at great monetary expense to you?? Thus my post, that seek a qualified repair shop, spend the money and get it fixed right,, the first time..If you want guesses?? heck I can give you plenty,, But with out a qualified person actually testing your car,, no matter what their qualifications,, thats all they are is guesses.. I tryed to give you best advise I could to help you.
