I had changed what I thought was #4 coil, which is the one specified by diagnostics.
Not being familiar with British engines, I changed wrong coil.
After months of head scratching, fooling with fuel injectors, computer, air flow, etc. I realized I had changed wrong coil.
Put new coil in #4 and now runs Beautifully.
At one point was throwing 7 or 8 codes, all attributed to this one coil misfire.
