Default 1988 Volvo 240 - LH2.2 1500 RPM Idle

All, I recently bought the vehicle in the title. I did some basic maintenance, oil change, flame trap, air filter, TB and AMM cleaning, and spark plugs. Speedometer and odometer is out, and the coolant temp gauge is not working. I am onto to figuring out those issues and plan to bypass the coolant board, change the coolant temp sensor, and fixing the odometer gears. Would any of these things affect the high idle I am experiencing? TPS seems to be positioned correctly. It is idling right at 1500 RPM once it has idled a bit (starts at 1700, then goes down). If it matters, it is a manual transmission. Thanks!
