I have a 1991 xj 6 has spark has fuel very hard to start dies when you press accelerator replaced plugs and rotor bug and fuel filter. I've replaced the plugs rotor button and fuel filter and wires have to feather gas to get it to start then it bogs at low rpm clears up a little at 3000 or more rpms dies under heavey acceleration
