Poor idle problem!!

Ok so Ive got a 89 240 with sr20det red top. the swap just got done about a week ago and after startup we have a really bad idle. almost as if 2 cyl arent firing all the time. All vacuums are fine, The injectors have 12v and are pulsing fine, and good spark. The plugs are carboned up so I know its running rich. What are some possible problems Im facing. thanks in advance.

you should try bypassing the iacv put a rubber cap on it ant on the outlet from the intercooler pipe and turn down your idle some if you still have the problem its something else but i still recommend you bypass it because they fail alot on sr's i got this info from durdan a while back so it should be accurate he an sr genius
