1993 Mercury Grand Marquis GS 4.6L Poor Idle Quality, Hesitation, Surge, Cuts out
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 ...
