Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.Can you explain what you mean when you say it idle funny and gets loud. Where dose the noise sound like it coming from, does it appear to be in the engine or an external noise. Has the computer system bee scanned to see if there are any fault codes setting, post back with as much information as you can and we can work from there.
Has the computer been scanned and if so are you getting any fault codes?
I would do that next but before you do that, try resetting the computer, to do this disconnect both battery cables and touch them together of for a few seconds and then reconnect them , start the engine and allow it to idle for about 15 minutes and see if it relearns the idle speed.
