Everybody wants "Mechanic In A Bottle"!!!! There are no shortcuts here, if you can't pass an emission test then something isn't working right! Start by cleaning and regapping the spark plugs. Pull the fuel injectors and have them cleaned and tested. Fix ALL vacuum leaks. If the mileage is high adjust the valves and replace the O2 sensor. Change the air filter. Drain your "cocktail" of fuel and put in fresh premium gas. You can easily check the timing and if you have to you can reach the distibuter to adjust it. When you pull the fuel injectors you will probably need new injector seals, you will need the copper seals anyway. A properly set-up and running Delorean easily passes emmisions testing. You should see a big improvement in your gas mileage too.
