I have a 95 GL with 162K miles that I drove off of the lot new. It started having a rough idle in park at around 80K. I've had a new alternator installed (not for the idle problem) and new plug wires and neither changed a thing as far as the rough idle. I read in this forum that it is a common problem with Contours and especially older ones.
I did replace the spark plug wires at the recommendation of the guy at the oil changing place. He said it would fix the rough idle. NOPE!
I have also heard that there is something in the intake system that could effect it. If you notice, there is a sensor in the hose leading to the big box over the engine intake. It is some sort of air flow metering sensor. I just know that it costs close to $200.00 and unless I am certian it will fix the problem I'm not buying one. Anyone else with any ideas?
