intermittently; acts like running on 4 or 6 cylinders then will act right after a mile.below 1500rpm, its terrible. at 2500 rpm, its hardly noticeable.

also...
whats the difference between injectors (AA,AB,AC,ad) why aren't they interchangeable?

AA are single shot...AB and everything else is Split Shot..... Programing is Specific..... You have to switch Computeres every time you switch Injectors or it will run like crap and waste Fuel.....What you are describing is classic CMP sensor failure...could also be a weak fuel pump and burn't UVC harness...What does the oil cap smell like ?

problem solved(or at least averted) I found the wire to fuel heater unplugged and touching metal.Problem hasn't shown up since.

That will do it, but I'm suprised the Maxifuse #22 didn't blow. Cheers1
