I have a 2002 hyundai sante fe 2.4 , 4 cylinder engine auto transmission.
When cold idles around 1000 rpm, when it warms to operating temperature it is at 2000 to 2250 rpm in park or neutral, in drive or reverse 750 rpm.
Replaced tps, iac, maff, pressure regulater, a few times. Replaced bad vacuum lines smoke tested, and still cant get idle down.
I would appreciate any input or ideas, thank you.
