What causes an engine not to idle?
The air throttle valve is a unit located between the engine and the air cleaner. If this valve is clogged and air does not flow, the engine cannot idle. Many mechanics start by replacing coils, plugs, fuel pump, air cleaner, plug wires or engine sensors. This will be futile because what the engine needs is air to run.
Why is my car stalling at idle?
Stalling problems trace back to three primary causes: a lack of fuel, not receiving enough air, or insufficient power. Common reasons include an empty gas tank, a faulty fuel pump, a bad ignition coil, fouled spark plugs, water in the fuel, or a failing sensor.
Why my car RPM goes up and down at idle?

What does it mean when your chainsaw won’t idle?
An air leak around the intake boot or head gaskets will result in lower compression pressures and your chainsaw won’t idle properly. You can tug the starter rope to get a feel for the compression levels, or you can take the chainsaw to a shop where they will do a compression test.

What causes a car to stall when idle?
A defective idle speed control system may prevent your engine from getting enough air to idle properly. A clogged catalytic converter may also cause stalling or lack of power when accelerating. If your vehicle is diesel powered, a dirty diesel engine filter may cause it to stall. A drop in fuel mileage is a sign of a clogging engine filter.
