I have a 99 grand marquis with 103**** miles the car was running fine intill the day i cleaned the TB after i cleaned it i put all back together. Once done i started the car and it was high idled so i turned it off and disconneted the battery for like 30 mins or so and still the same. I was getting the code for idle air control valve so i replaced it and nothing changed and i also changed the EGR and nothing changed. Im starting to run out of options here so if some one can help me i would really appriciate it. Thank you. Oh and by the way i did look for any vacuum leaks and didnt spot any..
