Car Idle Rough when Ac is On

If you’re like many people, you’ve experienced the frustrating experience of your car idling rough when the air conditioning is on. This issue can be caused by a number of things, but one of the most common is a faulty thermostat. If your car’s thermostat needs to be replaced, there are a few things that you can do to make the process as smooth as possible.

What is Car Idle Rough?

When you’re driving in your car, the idle speed of the engine can be rough. The idle speed is how fast the engine is running when it’s not moving, and it can make the car feel jerky or unsteady. This is especially common when AC is on, because the fan blades cause the engine to spin faster, creating more noise and turbulence.

There are a few things that you can do to try to fix this problem. First, try to get your car’s idle speed adjusted so that it runs at a smoother speed. This can be done by adjusting the throttle or transmission settings, or by using a car idle adjustment tool. If that doesn’t work, you may need to replace parts of your car’s engine or transmission.

How to Fix Car Idle Rough

If your car is idle rough when the AC is on, there are a few things you can try.

The first thing to check is whether or not your AC compressor is working properly. If it’s not, your car may be struggling to keep up with the demand for air.

If your compressor is working, but your car still idles rough, you may have a problem with your air filter. It’s probably time to replace it.

Conclusion

If you’re experiencing an idle roughness when your car is set to automatic, it could be due to a problem with the air conditioning. By checking the pressure in your AC system and making any necessary repairs, you should be able to get your car back on the road smoothly and without issue.
