2001 Disco 2 (v8). I put new 8mm kingsb-wires, and bosch (iridium) plugs in. I also put new plenum (and up) gaskets. torqued down lower intake/ pan bolts. compression test is 125-130 on all cylinders. I switched #6 with #2 and misfire moved to #2, but still misfired on #6 also. I suspect coil pack 2 is running lame. can I switch pack 2 with pack 1 - will this work? (how do i do it? do i have to reverse so Coil pack will still clip? HOw?)

 

P.S. I also put new O2 sensors (all 4) judging by the plugs on misfired cylinders it's running rich.
