I have a 1996 Mercury Grand Marquis. 4.6 v8 and about 109,000 miles. As of yesterday I could only start my car when slightly pressing down on the gas petal. And in order to keep it running while stopped or parked I have to slightly press down on the accelerator petal. A few days prior to my newly acquired problem I added some generic gas treatment (the stuff that supposedly removes carbon buildup from fuel injector heads/carburetor) though the tank. This leads me to believe my efforts to improve my vehicle’s performance did just the opposite. Any ideas?
