RPM

Toyota Camry

I have a Toyota Camry 4 dr sedan 4 cyl. Mileage is 140,000.
I have a problem usually in the morning.
whenever I start my car RPM goes down until it engine dies out.
I have to step firmly on gas pedal for a while before(maybe 2-3 mins.) With high RPM before it goes normal.
OR
after I switch the key on, I step on the gas pedal three times then start the engine and wait until the RPM is high enough to maintain the normal idle of my car.

BUT during the day, once I start the engine on, there are no problems with the RPM(idling).

hope somebody can enlighten me on this problem.
thanks.

Try checking the CTS/TPS/IACV

CTS: Coolant Temperature Sensor
TPS: Throttle Position Sensor
IACV Idle AirControl Valve

You need a manual or take it to a shop and have them scan it/serial data to find out what these sensors are doing
