My Hyundai accent 2004 seems has problem with idle... when A/C is running RPM is in 500. I tried to adjust the idling cable still same problem occurs. Please help...
Have you checked for vacumn eaks
Throttle position sensor could be the problem
Emmission control parts
You mentioned idler cable
Well there may be a second idler control cable
Some vehicles come with a double cable adjustment
The second adjustment is right above the gas pedal
Turning screw
Alternator giving out not producing charge needed
But overall if your cars idle bogs down the likely culprit is your ac bout to go out
The bearings in compressor wear out so it pulls more on the engine
In turn bringing rpm's down
Your car needs routine maintenance
Ac is an expensive repair so i suggest bypass belt till you can pay to have it fixed
Testimonial: "Thanks for the reply i'll check all the suggested cause of idle problem..."

the tps (throttle position sensor) could be causing the problem
SOURCE: 2004 hyundai accent. trouble filling gas tank
The fill tube for the fuel tank is either clogged with something or the anti-siphon feature (what stops people from stealing your gas) is fouled up. The tank and fill tube have to be inspected.

Hi, how many miles are on the vehicle? First thing would be a tune up. Then from there it could be a lot of things. dirty fuel injectors etc. Start with the easy stuff like tune up and fuel additive and progress from there.
Thanks,

If the idle sounds low you may need to clean the throttlebody or check the idle air control valve, this valve should raise the idle a little when the ac is on to avoid a low idle and possible stall. the other thing is to scan computer for any codes to see if it is misfirng , this can be caused by a bad plug or wire.

Hi there. The most common problem is the throttle body. Buy throttle body cleaner and spray on rag. Using a long nose pliers wrap the rag and clean the throttle from dirt while you hold wide open. Next disconnect the battery and wait 1min. to delete the computer memory. Reconnect the battery and drive for 10 minutes with ac on. At this point the computer will learn the new idle speed.
Good luck
