So last couple of days had a bit of rough running, figgering it was a coil, but was intermittent . So scanner on, cyc 7 injector issue.
Checked coil and changed it over to double check, no change, so not coils.
Bit of Google help and checked the wiring into the injectors first, bingo, one of the plastic connectors into the top of the injector on 7 got brittle and the right wire was bouncing in and out, easy fix, back running sweet :)
