I have the same problem with my 98 sc1. After the car is warm I disconnected the Idel Air Valve Wire, the service engine light come on but the car didnt have the high idel problem. (the idel air valve also control the cold start "choke" you have to have it connected or it might quit from low idel and for your car to cold start the next day) I replaced the Idel Air Valve $45 and PCV Valve, and cleared the computer codes. Helped alot but didnt completely fix the problem. My next step is to buy a gasket for the throttle body.
high idle problem on a 1997 sc1 when car is in gear

It has a timing chain.
I would first check the transmission fluid level.
It is probably a linkage problem
On a 13-speed double over, if your low gear will not work, particularly when climbing hills, there is likely a problem with your transmission or shifter. Many times the problem is seen where low gear will not work and high gear will, indicating a problem with the mechanism.
The high preasure goes from the pump to the gear and the return goes from the gear to the pump resirvoir.
If the transmission on a 1999 Chevy 4x4 will not shift into high gear, there could be a problem with the shift solenoid. There could also be a problem with a broken belt inside the transmission.
A transmission that is sticking would cause a 1997 Plymouth Grand Voyager to die after shifting it into gear. A problem with the ignition system could also cause this.
A common problem with alot of Volvo's is the Overdrive. Basically the high gear. If it wont shift into high gear it means that the "Overdrive" is activated and won't shift into high gear. You need to see if there is a little upwards pointing arrow on your Dashboard Cluster. If there is then you need to replace your Overdrive Solenoid.
My 1997 Dodge Avenger automatic transmission stays in 2nd gear a the time. What seams to be the problem?
