2001 Mercury Grand Marquis GS 4.6L Poor Idle Quality, Surge, Misfire
Posted to Ford Driveability on 2/19/2015 19 Replies

When you start this vehicle up cold (40 degrees or less) it will want to chug and stumble like its losing fuel. Doesn't stall but after about 20 seconds of running it clears up and the vehicle runs fine with no drivability issues.
