Emission problem

latinowarrior · 11-26-2005, 06:46 PM

I need some help! I have a 84 Eldo Birz with 145,000 miles. I failed the emission test and I need to know what I will need to do to pass the darn test. I got a high reading in the NOS and CO. I plan to give the Eldo a tune up and replace some parts (spark plugs/wire, Disp Cap/rotor, igniter, egr valve)and maybe the Cat converter. Any and ALL help welcomed.

That should do it, although you might get away with just cleaning the EGR valve. The igniter/module usually either works or not so I would skip that until after you do the other things.

Blocked/carboned egr passages on the HT4100 were very common, watch out for this.

Well, I repaced all the above mention parts and YES the EGR was totally clogged. She seems to run a little hard so I will be taking her in for a tune-up. I am still waiting for the cat so I can replace the old one. I hope once all the work is done she can pass the smog test.

Well, I now have a sooty, wet black smoke coming out of the tail pipe. How can I fix the problem. I would like to have her running this summer. HELP!!!!

Any check engine lite?

Check engine light is not on.

Yea, I had the same problem. I had to clean the carbon build up in the EGR port, then it passed no prob.
