Why does my Car start but not stay running at idle?
Once it starts, as long as my foot is on the gas, it stays running. The second my foot is taken off, it turns right back off. My car has 20000 miles. My car has an automatic transmission. You may have a dirty or failing idle air control valve.
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.
Why is my idle air control valve not working?
You may have a dirty or failing idle air control valve. The idle air control valve reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle.
What to do when your dirt bike won’t idle?
Whether you have a 2 stroke or a 4 stroke, if the idle adjustment is set too low, the engine won’t stay running. Turn the idle screw in and see if your dirt bike stays running. You may have to turn the idle down slightly as the engine temperature warms up. Did You Warm The Engine Up?

Why does my car stall when I Turn Off the engine?
If your car’s engine stalls while running or at idle, it is a clear sign you are having some problems with your fuel pressure. This may be due to fluctuations and sudden drops of the fuel pressure. Today’s electronic cars have a fuel pressure sensor that intelligently calculates if anything is going wrong with the fuel pressure.
Why is my car cranking but not starting?
One, your engine is having trouble producing a spark. Two, your engine is having difficulty obtaining fuel. Three, your engine is creating compression. What is so pivotal about these three components is that to successfully run and drive the vehicle the engine needs fuel, compression, and a spark all working simultaneously.
What causes a car to die at idle?
When a car dies at idle, the last thing that drivers think of is a problem with the spark plugs. Gasoline engines require these small gadgets to deliver a spark to ignite the fuel air mixture in the combustion chamber. If you have a diesel engine, then this is something that you don’t need to worry about.
Why is my car not running at idle?
Running fine at idle and low speeds around town but struggling and stalling under on-ramp acceleration likely means low fuel pressure. It has enough for idle, but can’t keep up as RPMs increase under hard acceleration. Then the engine starts up again because startup requires little fuel.
Why does my car stall with no fuel?
Before the introduction of direct fuel injection, most vehicles did not have a sensor to read fuel pressure, meaning if the fuel pressure is low or off, you will not get a code, but you will have poor idle and stalls. Erratic idle before stalling could be a vacuum leak on the intake side.
Why is my car engine not keeping up?
It has enough for idle, but can’t keep up as RPMs increase under hard acceleration. Then the engine starts up again because startup requires little fuel. In this case, check the fuel pressure from the fuel pump. Surging and stumbling at medium load can also be due to a faulty EGR valve.
What causes a car to start but not keep running?
The engine requires the right amount of air and fuel to mix together for ignition. If there is a fuel leak somewhere, then the correct amount of fuel may not make it to the combustion chamber. This might be enough to allow the engine to start, but not keep running.
What causes a car to stall on a cold start?
It also manages the idle under changing engine loads, like when you kick on the air conditioning, turn on the headlights, or turn up the radio. When the idle air control valve malfunctions, you may experience a rough idle or the vehicle may stall entirely. This is especially true on cold starts.

What causes a car idle to be unbalanced?
Since a smooth idle depends on just the right mixture of fuel and air, there can be many possible places where that combination is getting unbalanced. Some of these causes can be simple, and some can be complicated.
