Ok this may be a long one my wife's 3.5v6 trooper has been causing a few running issues it seems to missfire on one bank so thinking it may be the usual inlet manifold leak which I have done before I redid that seemed better but still not right so did the usual comp test which seems fine between 195psi and 205psi across all 6 cylinders it has a gas kit So I got into that and the injection times on one bank are different to the other so at idle it runs 5m seconds  on bank 1 and 7ms on bank 2 I replaced the o2 sensor  but it only uses 1  for both banks so I doubt it's that seems to have  good sparks when I pull the coil packs a bit I can hear the spark jumping  the EGR has been blanked for years any ideas I'm wondering if the ecu is on its way out is this common
