[DML] Re: Failed Emissions

Thanks for all the good advice to date. I was hoping it would be the least 
costly of all the items I listed!! To your response David, I don't have 
specific readings but for the NOX readings, the applicable standard is 3.0 
grams/mile and the Delorean is putting out 5.4 grams/mile. The other 
readings were: Hydrocarbons (HC) .10 g/m (standard is 2.00 g/m); Carbon 
Monoxide (CO) 1.3 g/m (standard is 30.0 g/m) The car was fully warmed up 
for the test. The car runs fine -- perhaps a bit hesitation when cold but 
nothing really major to be concerned about. While the NOX reading is not 
excessively high, if all that is required is a tweak of the air /fuel 
mixture, that makes me happy. Is this something I should attempt or just 
take it to the professionals?

Mark,

I am assuming that car failed at the idle portion of the emissions test. If 
so, I would start with rechecking the timing and also adjusting the fuel 
mixture at idle. These are not difficult things to do. The problem is you 
need a 5 gas analyzer in order to know which way to turn the mixture screw 
and by how much to achieve the desired results. You will need to take it 
into a shop unfortunately. Good luck.

David
