I had the 0440 code and ended up having a split vacuum line from the throttle body to the MAP sensor. Its cheap enough to just change as I assume its probably original from 96.

ok problem fixed for code 0300 i bought 2 new coils, 4 new boots, coil housing, and 4 dcelco spark plugs. total $141 at advance autoparts.
the 0440 problem it comes and goes i just make sure the gas cap is tight and it goes away, but always comes back after a few months oh well.
