04 4runner misfiring on bank 2

[cwaite2]

ive got a 04 4runner with a 4.7 thats misfiring on bank2 only.both o2 sensors are slow to respond.ive replaced both sensors but problem still present.swap coils but still there?it runs fine when driving down the street but at idle it skips?anyone have dealt with this before?injectors/convertor?

I know on the 3.4 engines a miss like that can normally be tracked to a bad ground for the coils, not sure on the 4.7 but looking at coil grounds is easy enough and wont cost ya nothin but a little time.
