Question about 1995 Mercury Grand Marquis
My 1993 Grand Marquis starts up fine,but if i try to drive off,it barely goes 10mph.Also starts backfiring..simply can't/wont rev up past idle speed (which runs really smooth)
..once it warms up,then it seems fine. I've changed EGR sensor,Temp sensor,and now TPS sensor.
Clean the MAF sensor with electrical cleaner then blow dry with light shop air or just let air dry.then disconnect battery for about 30 minutes to reset keep alive memory.Should take care of your problem.
