Have an 2002 Ford Explorer XLT 4wd. After I had the Valvue cover gaskets replaced have been getting code 1506 IAC idle to high. Replaced IAC plus had the garage to look for vacuum leaks, none found what would be causing this code?

Had Value cover gaskets replaced on Sat 2/12/12, light not on before then, it is idling around 750 to 800 in park and around 500 in gear

Is sounds like a vacuum like or wring connector has been. Please inspect and get back to us :-)
