I would replace CATalitic converter, this car is old, plus a tuneup is 100% necessary , spark plugs wires, ditributor cap & rotor, plus both the air & fuel filters need replaced. change oil & filter. then you will pass emissions test. and your car will run like its suppose too. if you don't do all this , then buy a new car !
