Question about 1997 Chrysler LHS
The throttle position sensor may be misaligned. This tells the computer how much throttle is being applied, and when they go bad, or come out of alignment, the idle tends to get up there. If that's not the issue, remove your air cleaner, the housing and everything until you get to the MAP sensor. Give it a good spray with carb cleaner, let it dry and replace the air cleaner with a new one. If the MAP sensor detects minimal air flow, the computer jacks up the idle to compensate.

If you go to advance auto they will scan the car for free. if you write the codes down and update your question it will be easier to eliminate some of the sensors.

with a 2002 Concord 3.5 V-6, what should the rpm be at 60mph? 70 mph?
I'm not sure if the overdrive gear is lost in the tranny, but the transmission light is on.
