Failed Inspection - 90 Vette

Anybody help me pinpoint the problem.

90 Vette Coupe, 120,000 miles. Houston Tx: CO2 state emission allowance
failed at both low speed and high speed.\
I have heard tapping noise from the passenger side of the valve covers
(possible lifter), would this cause
CO2 emissions? This could also be a break in the manifold gasket, again,
could this cause CO2 emissions?

Any other possible problems?

Since your state has requires tests (whew glad Florida doesn't :-)
I would think there are local mechanics that very knowledgeable
in what to look for. That's kinda a specific field I'd think.

Maybe a Google search for Co2 emission failure.

When was the last time you cleaned your injectors???

Its been over a 1 1/2 years (when first got car). I'm looking to fix the
tapping problem and
might as well see what else I can replace while the valve covers are off.
The distributor system
is new (about a year), but I'm also leaning towards a minor tune up. Thing
is, the "service engine
soon" light does not come on to try and pinpoint with diagnostics.

Thanks Ric, I'm thinking of changing titles to where my brother lives so
that I don't have to mess with the
emissions. I only drive the car occasionally. It goes into my mechanic's
shop on Monday evening to see
what he can find.

Every hear of a clicking injector, don't count it out. I use the broken
tubular shaft from a golf club as a stethoscope to pinpoint the noise.
