Fuel system should be where to start.
You might need to check the spark plug wires, fuel filter, and check the vacuum hoses.
All you have to do is unplug the battery for about 10 minutes. That will reset the system, then drive the car or leave it idle for about 15 minutes. If it comes on again, then you have a problem and you should do a diagnostic test.
the RPM should idle 700 - 900
The idle adjust screw is on the throttle body. The side of the throttle body that faces the front of the car should have a dime size flathead screw towards the upper edge.
You dont adjust the Idle disconnect the battery for 10 mins and reconnect and the computer should relearn it idle .

Check the idle sensor if you have one.
Most likely because it can't idle. You need to check if the idle control valve is working (if you have one), also try adjusting the idle control screw.
You can't. Toyota Camry uses throttle position sensor to adjust idle. If your car does not idle you need to check computer for error codes. If you do not have any, most likely you will have to do tune up on your engine and maybe even fuel system. But starters check the air filter and replace if you did not do that in a while or if it looks dirty.
You cannot. As it is EFI, therefore controlled electronically, you would need to plug it into a diagnostic computer to access the idle speeds etc.
Check fuel delivery pressure Should be: at idle 13-20 psi with ignition on and motor off 23-31 psi
You dont , it is controlled by the ECU , the is an "Idle Speed Control Valve" Which is located under the throttle body. should check it to see if the valve inside of it is stuck .
