1990 eclipse gsx odd idle (possibly ecu?)

ik i have a intake gasket leak...i gotta torque the bolts down some more ive eliminated all other Boost leaks...but with Boost leaks ive never encountered the rpms jerk this way....nor have i encountered an idle like this..its almost like a miss but i know its not... mods done... 480cc injectors 2g maf rs bov set to stock 2g exhuast manifold timing is dead on, new spark wires, new ngkr plugs think it could be the idle control on the ecu??? also i just recently rebuilt the head and the block has about 9k miles on it

1990 Mitsubishi Eclipse weird idle
I have a 1990 1Ga Eclipse GST. Ever since i bought the car it has a weird idle to it. Been told it is possibly a slightly bent Exhaust valve in cylinder 1, or my turbo manifold is leaking, or my timing is off.
