My 1992 saturn keeps failing the emissions test

it is probably bunring oil which is causing this,,,if it is burning oil you can try this to help it,sometimes it works and other times it doesnt,,,,,get the car good and hot,remove the spark plugs and get top engine cleaner and dump it into the plug hole,let it sit overnight if you can,,,,disconnect the ignition module and put rags over the plug hole and crank the engine a few minutes with breaks inbetween to get all the left over cleaner out the engine,,,,then plug the ignition module in and put the plugs in,it may smoke really really bad,,,just keep running it,,you may have to put foot on gas to start it,,,,,let it burn all the **** out the cylinders and then change the oil and get new plugs and that should help the oil burning if it is a oil burner and hopefully help the emission readings,,
