86 GN that seems to idle ok but breaks up and pops back through the MAF when you try to rev up the engine even a little it seems to hesitate and break up really bad in addition when this occurs the factory boost gauge will jump up to 5-8 psi good fuel pressure, has a rich exhasut smell, all readings on direct scan seem ok-New coil pack, replaced MAF, EGR, sensor, plugs, wires,swapped out computers, plugged and unplugged direct scan (not trouble coding at all). Just replaced PCV grommet and fuel injector O rings (Had a vacuum leak sound which the O rings fixed). Don't seem to have a problem with battey cables as other people had. Any ideas guys.
