2001 Mercury Marquis Repair Question
Car doesn't stay running
well you are putting a load on the electrical, so the battery and the alternator will need to be checked, also check your IAC(idle air control valve). could be faulty or just dirty.
How do you check the IAC or clean it? Thanks.

you have to take it out of its bore, which is located on the throttle body,by the way you will clean the throttle body while your at it, you will need help because someone will need to turn the key on(not start)and you will observe if the "pintle of the iac moves in and out, like little steps. if it moves in and out, then it should be fine.
