I'll just get to it, when I have the car on and let it sit, the idle dips down and goes back to normal instantly but if I let it sit longer it will dip again and sometimes just die. I just recently changed spark plugs and cleaned my MAF sensor so I don't know what else the problem can be. maybe you guys can help me out. thanks

 

Look up "throttle body adaptation" - that may help. You could also clean the throttle body with throttle body or carb cleaner.

 

awesome, thank you, hopefully that will do the trick for me
