If your car is idling rough and not getting the fuel it needs when ac is on, there are a few things you can do. First, check the thermostat for proper operation. Make sure that it's set to the coolant temperature you're using. If the thermostat isn't helping, you may need to replace the cooling fan relay. Finally, if all else fails, you may need to replace the engine.
Introduction: Describe the problem of a rough idle when the AC is on
Rough idle when the AC is on is a common problem. The main reason for this problem is that the AC compressor takes up a lot of horsepower. When the AC compressor is on, it takes power away from the engine, which can cause a rough idle. There are several ways to fix this problem. One way is to adjust the Idle Air Control (IAC) valve. Another way is to adjust the throttle position sensor (TPS). A third way is to adjust the throttle cable.
Causes: List a few possible causes of this problem
One possible cause of a rough idle when the AC is on is a dirty air filter. If the filter is clogged, it can't properly circulate air and can lead to problems with the engine.
Another potential issue could be a problem with the engine's ignition system. When there is a misfire, it can cause the engine to run roughly.
If neither of those solutions seem to be the problem, it's possible that there is an issue with the AC compressor itself. When the compressor kicks on, it puts extra stress on the engine and can lead to a rough idle.
Solutions: Offer several solutions to fix the rough idle
One possible solution is to replace the air filter. A dirty or clogged air filter can prevent the engine from getting enough air, which can cause a rough idle. Another solution is to have a mechanic check the engine for any problems that could be causing the rough idle. There could be something wrong with the ignition system, the fuel system, or another component that is causing the problem. If the mechanic cannot find and fix the source of the problem, then it might be necessary to replace the entire engine.
Conclusion: Summarize the article
When the AC is on, the engine works a bit harder to power the compressor. This can lead to a rough idle and decreased fuel economy. There are several things you can do to fix this problem:
1) Make sure your AC system is properly charged with refrigerant. A low charge can cause the compressor to work harder and lead to a rough idle.
2) If your AC system is low on refrigerant, have it recharged by a professional.
3) Check your air filter and replace it if necessary. A dirty air filter can decrease airflow and cause the engine to work harder, leading to a rough idle.
4) Inspect your spark plugs and ignition coils, and replace them if necessary. A misfiring spark plug or coil can cause the engine to run rough.
What causes a rough idle?
There are many things that can cause a rough idle, but one of the most common is a dirty air filter. Other causes can include a bad spark plug, a vacuum leak, or a dirty throttle body.
What can I do to fix my rough idle?
There are a few things you can do to fix a rough idle. One is to check the air filter and make sure it's clean. Another is to check the spark plugs and make sure they're in good condition. You can also try adding some fuel injector cleaner to your gas tank. If none of those things work, you may need to have your car serviced.
What is the best way to fix a rough idle?
A rough idle can be caused by a variety of issues, so the best way to fix it will depend on the specific cause. In some cases, a rough idle can be fixed by cleaning or replacing the air filter, adjusting the carburetor, or replacing the spark plugs. In other cases, more extensive repairs may be necessary.
What is the best way to fix a rough idle when the air conditioner is on?
There are a few things that can cause a rough idle when the air conditioner is on. One possibility is that the air conditioner is putting too much load on the engine, which can cause it to stall or run rough. Another possibility is that there is something wrong with the air conditioning system itself, which can also cause the engine to run rough. If you suspect that the air conditioning system is causing your engine to run rough, you should have it inspected by a mechanic.
Why does my car have a rough idle when the air conditioner is on?
One possible reason for this is that the air conditioner compressor is putting a load on the engine, which makes it difficult to idle smoothly. Another possibility is that the air conditioner is not functioning properly and is causing the engine to work harder than it should.
What causes a rough idle when the air
There are many possible causes of a rough idle, but one of the most common is a dirty air filter. A clogged air filter can restrict the flow of air into the engine, causing it to run rough. Other possible causes include a defective fuel injector, a vacuum leak, or a faulty ignition coil.
