1993 Mercury Grand Marquis GS 4.6L Poor Idle Quality, Hesitation, Surge, Cuts out
Posted to Ford Driveability on 10/8/2012 12 Replies

Vehicle comes in sputtering most of the time...once in a while, it will start and run just fine. Vehicle seems to load up, and then backfire when cleared with throttle blip. Work listed was done at another shop. Runs on highway pretty decent, do not feel cats ...
