92 Town Car, Will run and idle for hours, but give it gas and it bogs down, even stalls or get a backfire type noise. Car did sit for 3 years, could the old gas cause this? New fuel filter already installed.
Can start vehicle and idle is fine. If I feather the gas I can get the engine up to high rpms and it seems fine. If I press gas pedal all the way down it is like someone is squeezing the fuel line, get a popping noise from engine, and it usually will in a rough chugging way, get up to rpms. About 80% of the time, if I am idling smooth and put it into gear, it stalls.
