91 Camry surging

Hello I have a 91 Camry just bought it and when I slow or stop it starts to surge up to 1500 to 2000 rpms ( normaly runs right around 1000 rpms at an idle)  it does not hapen all the time but most of the time I was thinking maybe a map sensor but not sure can you please help.

You maybe need to adjust the idle speed, on top of the intake manifold, near where it says EFI, there a small black rubber plug, pull it out, turn off everything in the car, then turn the screw in where the plug was to change the idle speed. Or it could be that you need a new Idle Control Valve

You have two problems. The surging is from a dirty throttle body and /or air filter. The selector light could be from a bad selector switch or internal transmission problems. Have the car scanned for codes.

Check the PCV valve and vacuum lines for leaks. You also need to check the Vacuum advance as it sounds like it might be sticking a little.

Is the check engine light on?

A major cause of surging is either air leaks between the air flow meter and the engine intake manifold, or a bad or mis-adjusted throttle position sensor.
