You can't do it with out a tech 2 scanner, so your going to have to go back to the Mechanic to have it reprogrammed. As long as it's running rich, your going to have bad fuel economy and will not pass the emission test when you have to have it done. Good luck and glad to know you got your car running almost 100%

SOURCE: fuel mixture is too lean
many of the late model cars & trucks can't be
adjusted some of the carbs are preset some you can force and some don't have an adjusting screw for the jets if the carb is in good working order but needs a bit more fuel you u must adjust the float for more or less fuel check to make sure the float valve is clean free and not sticking ..

On a carbureted engine(the days of old) I had a method of my own
which always seemed to do really well.
Warm up the engine to operating temperature and make sure there is no
operation of the automatic choke.This should mean that the choke flap in the top of carb is standing vertically offering no resistance to airflow.
Hook up a tachometer if the car has'nt got one.
Note the idle speed in PARK.
Turn the fuel/air adjusting screw underneath carb's right or left sideI(NOT the idle speed set screw) IN and note the rpm as you do.If it raises a little,you are getting close.
Go ahead and turn that screw in all the way and lightly seat it(count the turns in from the highest idle reading),then back it out to the highest reading.NOW turn it in slowly until you see the RPM drop slightly.
Now back it out a little so you are at peak RPM again.
REPEAT this with the other side's fuel/air screw.
After you have gained this higher RPM (maybe), then set the idle speed control screw to desired RPM, and be sure to get in the car and while holding the brake,put the car in DRIVE to make sure the idle doesn't drop too low. don-ohio (:^)

you have a vacuum leak some where take a can of brake clean and spray a little on the vacuum hoses and if the idle goes up then that is where the leak is
