Hi, I have a problem with my Ford crown victoria 1995. It was sitting about 1,5 years. So I replaced plugs, plug wires, ignition coils, fuel filter, clean MAF. So still have the problem when i riding on hill engine start loosing power and speed. And when I accelerate from 30 to 40 miles/hr engine hesitates and shaking. Any ideas? Thank You -
