Assuming a US engine, it's accessed from the passenger side just in front of the throttle body, screwed into the intake manifold with a 1" black hose running to it. It is considered a maintenance item so if it has never been replaced, you should probably just replace it. They are inexpensive, like ten bucks.
try checking that there is no moisture build up in the sparks as this will cause it to idle rough but drive fine. if u do find moisture try spraying some crc 556 or other lubricant in the spark cavity and check the spark plug gapping. if its still idling rough after that take it to a garage :-)
it doesnt matter they are both better than subaru
is the check engine light on? if so it may be the coolant temperature sensor...happened to me...if it doesnt turn over at all try the starter or the battery
with regular maintenance, and if the body doesnt rot off it, it will go forever. Mine is very rusty, but has 231,000 miles.
