this may sound silly, you didn't forget to remove rags before reconecting pipes?

Have you determined which 4 pots are running? Have you done the standard diagnostics to determine what is actually not working?

obviously the gtr cooler is second hand? is there any damage to the intercooler? if there is a crack in it or a hole then the car will be running rich and fouling up the plugs causing it to drop a cylinder or 2

i found it. i fouled cylinder 3,4 cause the bov return pipe was split and a vacuum hose under the throttle body was split as well. 2 new plugs and a some new pipes and its goin like a champion again. thanks for all your help guys.
