Emission Test Failed! Help!


Ok, I'm not very good at diagnostics.  I have a problem with the V8 I need
help with.  It failed the emissions test here yesterday.  The Oregon State
standards are 220 ppm maximum hydrocarbosn (HC), 1% maximum carbon monoxide
(CO), and 6% minimum CO + CO2 at two engine speeds:  idle (~ 900 rpm) and
2500 rpm.

Our V8 got:

engine speed          HC ppm max            CO (%) max          CO +CO2 (%) min

901                    396                   2.63                    16.2

2323                   213                   0.85                    15.6

Does anyone have an idea of where I should start?  I've never had a car that
was this far out of specs.  No wonder we get less than 20 mpg!

TIA.
