Ford

I baught this 1995 ford thunerbird , the car was well taken care of and pampered and clean. i baught it and k it for a smog check . the mechanic said it was in nice shape but the co emision was unusually high and it barely made it through the testing ! . ..so i was wondering what could i do to take nice care of it and make sure it doesnt fail in the next test ( in one year ). .i talked with him and he said there are aftermarket fuel treatments to clean the fuel lines and he said it might need a new catalytic converter , the car only has 79 k miles on . so what should i do ?

I would replace the oxygen sensors and replace the spark plugs,air filter,fuel filter and pcv valve these items should help clean up your im test next time as these all will bring your emissions down considerably plus make sure you double check the sparkplug gap as they are not always set properly.periodic oil changes will also keep emissions down nice luck with your new car
