    Liberty had symptoms of a clogged converter. Replaced both converters and upstream O2 on bank 2 (same side as clogged converter) started vehicle and it ran very rough with no codes. After 2nd start (rough) code was thrown for cylinder 1 misfire. Swapped coils around to chase code but nothing. Replaced all 3 coils and 6 plugs and nothing changed. Replaced cam sensor and again no change running condition. Confirmed all injectors operating, no coolant in cylinders. Pulled all vacuum hoses and tested for leaks.
    At the end of the line with no codes being given. Any ideas
