FAILED SMOG EMISSIONS HIGH CO
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 !

Did it rain before it happened? (Humidity?) It happened to my 2000 Maxima. A few days later it was OK. I also checked under driver's seat. I thought maybe I was pushing on a wire with stuff I had there..?

If the car idle on high rpm check if when you will step on the gas pedal over 2500 3000 rpm the car will start shaking and the will die if thats happening then check your mass air flo sensor ,or if there is no air leak that avoid the mass air flo sensor

these cars are known to have injector failures and that would make you fail a emmission test easily. also i would reccomend looking at your oxygen sensor.
