This is a 20 year old car- that's like 200 human years old- First- it passed the smog test so why worry? Secondly, a car as old as yours will have a general degradation of all the parts in a system, so it's likely that you won't be able to bring your engine up to perfect smog levels just replacing one or two parts- Finally, I LIKE your idea of a "good blow out"- this is called an "Italian Tune Up" and a lot of times it woeks wonders with a car that is only rarely driven- how does it work? Think like an Italian race car driver at Monza- floor that baby, race it, get it up on the freeway at night and find out what the top speed is- of course, don't exceed what you feel is safe- the advantage of the Italian Tune Up is that it is cheap- and a bit of fun, too

In addition to what jam said, fill it with premium. It burns cleaner. Drive for about 30 minutes before you go to the inspection station. Your engine must be fully warmed up to operating temperature (195°F) in order to pass. If you have to wait in line keep the engine running and turn off all the accessories (radio, heater, A/C, lights, etc.). Keep the engine RPMs slightly above idle by keeping light pressure on the gas pedal. This will keep the oxygen sensor at operating temperature and prevent the computer from going into open loop (cold) operation. The computer needs to stay in closed loop operation. By doing this you should pass no problem. HTH. -Jim
