Summertime is the best time, right? The sun is shining, the birds are singing, and best of all, you can turn on the AC in your car and cool off. But what if your car starts idling rough when you turn on the AC? Don’t worry, you’re not alone. In this blog post, we’ll tell you why it happens and how to fix it. So keep reading to find out more!
What Are Some Possible Causes Of This Issue?
Well, it could be a number of things. It could be that your car is low on refrigerant. Or, it could be that your compressor isn’t working properly. Whatever the case may be, you’ll need to take your car to a mechanic and have them take a look.
They’ll be able to diagnose the problem and tell you what needs to be done. In most cases, it’s a simple fix that won’t cost you too much money. However, if the problem is more serious, then you may need to replace your compressor. But don’t worry, this is still a relatively inexpensive repair.
10 Reasons Why Does My Car Idle Rough When I Turn On The AC:
Dirty Air Filter:
One of the most common reasons your car might idle rough when you turn on the AC is because of a dirty air filter. When the air filter is clogged, it doesn’t allow enough air to flow through, which can cause the engine to run unevenly.
Faulty Fuel Injectors:
Another reason might be a problem with the fuel injectors. If they’re not working properly, they might not be able to deliver the right amount of fuel to the engine, which can also cause it to idle rough.
Incorrect Spark Plug Gap:
If the spark plugs in your car are not spaced correctly, it can cause the engine to misfire and idle rough.
Leaking Vacuum Hose:
A leaking vacuum hose can also cause the engine to idle rough. This is because the leaking vacuum hose will allow air to enter the engine, which will throw off the air/fuel mixture.
Worn-Out Spark Plugs:
If the spark plugs in your car are worn out, they might not be able to create the spark that’s needed to ignite the air/fuel mixture. This can cause the engine to misfire and idle rough.
Ignition Timing Is Off:
If the ignition timing is off, it can cause the engine to misfire and idle rough.
Clogged Catalytic Converter:
If the catalytic converter is clogged, it can restrict the exhaust flow and cause the engine to idle rough.
Dirty Oxygen Sensor:
A dirty oxygen sensor can cause the engine to run lean (too much air and not enough fuel) and idle rough.
Fuel Pressure Is Too Low:
If the fuel pressure is too low, it can cause the engine to misfire and idle rough.
The Thermostat Is Stuck Closed:
If the thermostat is stuck closed, it can cause the engine to overheat and idle rough.
What Have You Tried So Far To Fix The Issue On Your Own?
Have you tried cleaning the air filter? How about changing the spark plugs? If you’ve already done those things and the problem persists, then it’s time to take your car to a mechanic and have them take a look.
