Hi my 1998 Mercury Sable GS stalls within a few seconds of turning on. It starts up just fine but unfortunately it will die if i dont put it in to drive right away and start going or step on the gas to rev it. It can stall up to 4 times usually before i can get it moving. Also when i step on the gas it will acclerate really slowly and sometimes if I stop at a red light it will stall out and die. I havent had it checked yet because a friend told me about some fuel injection cleaner that i can get and i was wandering if that would be a good thing to try or if that would be a waste of time.
