I asking for a starting malfunction with my CRV 2002 manual transmission : Pre problem is prevalent in the morning, when I start the car the idle RPM goes to up 2000 instead of 1500RPM that usually I have observed, After about a minute when the car is getting worm , the RPM start to go UP and Down from 1000 to 2000 RPM with high regularity, after 5-10 minutes the RPM doing fine and stable at 600 RPM. The problem appear come out only when the car is getting cold. No matter if A/C is on or off.

Somebody can help to understand what append to my CRV

Many thank in advance

. Clean the Idle Air Control Valve (IACV):

. Check/replace the Engine Coolant Temperature (ECT) Sensor, which affects fuel injector pulse width. The ECT Sensor is a temperature dependent resistor (thermistor), whose resistance decreases as the engine coolant temperature increases. It provides a richer mixture when cold, leaner mixture when hot. They become corroded, due to not changing the coolant frequently enough, flood the engine, and waste a tremendous amount of fuel.
