Question about 1997 Mercury Cougar XR7
Well you could say that almost every part of the engine is part of the emissions system, but in the main in the trade we mean the breather pipes and the air intake system, if the motor has high mileage it could be that its burning a little oil and could have clogged the catalytic converter if you put some upper cylinder cleaner in to the air intake following the instructions on the can it could clean it out for you the chemical is not that expensive and its not that hard a job to do. if you still have a problem you will need to look at checking that none of the little pipes are blocked if they are just blow them out or use some carburettor cleaner to clean them out (off the car) and blow them dry.
hope this helps JR
