Can't stop the missing!

[TURB0]

Ok, my 91 gsx is being a pain. At all times, even during idle, it is missing. The idle is smooth though, it still boosts fine...it just sounds similar to a subaru boxer motor and has a lack of power. The plugs/wires that I have are nearly brand new, I tried using a buddies power transistor and coil pack as well. I even just replaced the timing belt and re-timed it. I have no idea what else to try! Any input?

Did you try adjusting your CAS to see if it clears up when all the way retarded or clears up all the way advanced. If it gets better in one way or the other I think it will point you in the right direction.

What octane fuel? Whats knock sensor condition?

I tried rotating the CAS both directions and couldn't find any noticeable change. 93 octane fuel. Pretty much brand new knock sensor. FIC 650cc's with less than 1000 miles on them too. I'm running out of ideas, haha. Ill check the timing tomorrow to see if it somehow jumped again.
