Throttle idle problem. It happens that when you turn on the car is running (jumps) between 1000 to 1200 rpm, and when the heat becomes unstable and jumps between 400 and 800 rpm. The problem is even greater when you suddenly add gas rpm jumps to 1500 rpm and stay there until you start the car, when I restart the car, the rpm jumps back again and becomes unstable between 400-800. Please if you have any suggestions or known what the problem is, please help me.

Engine erratic idling are usually due to faults with the idle control system. If the Malfunction Indicator Light is not showing, it could be due to dirty air passages for the idle control circuit, lack of coolant, misfirings or engine mechanical faults such as loss of compression, worn camshaft lobes etc.

For a start I would suggest checking the coolant level and have the throttle body together with idle control components cleaned.
