My continental is a 97 and has about 97k miles on it. The car seems to be idling a bit high. Sometimes in gear it will idle at 7-8 hundred, when in n or P it sometimes is 700 other times 1000. This is after the car is warmed up and has been running. Several times I've pulled in the driveway and the car is idling at 800 or 1000 in drive or park. If i'm not mistaken it was and should be more like 600 in gear and about the same in N or P. When I tried cleaning the iac I noticed the throttle body cleaner was dripping out the "top" I've cleaned mine on my 4.6 98 towncar and my 99 dohc sable. Neither had any type of leak like that. Could it be bleeding air all the time and harming economy/power as well as idle>
