Any trouble codes?
Is the ECU going into closed loop at cruise like it should?
TPS adjusted to 1v output at idle (warmed up)?
Vacuum leak? Any vac hoses pulled off of their connectors?
Compression?
Spark present on both leading secondaries at idle?
Timing and advance
Double throttle not opening?
When was the last time the injectors were cleaned?
EGR valve stuck open?
Check regulated and unregulated fuel pressure
Check voltage at ECU for TPS, AFM, water thermo sensor, both intake air temp sensors, boost sensor, barometric pressure sensor

check your wiring to the plugs.
the leading coil( at the front of the car) go to the Lower plugs,it doesn't matter if you mix the plug wires up.
.BUT the Trailing coil wires are specific.you need to put TI(marked on the COIL ) to the First TOP plug towards the front of the engine,The Last plug wire obviously goes to the TOP Rear plug.
