98 acura RL has check engine light on. When driving it will blink. OBDII scan shows codes; P1201-1206, P0300, P0183, P0175. Freeze Frame data: Fuel Sys 1 & 2 are Closed Loop; Calculated Load is 57.6, ECT is 176 degrees, SIFT B1 is 1.6%. Not sure where to go from here. Scan tool suggests MCM internal fault, IMA can malfunction. Looking for help.

I found the problem was a disconnected vacuum line on the Intake Air Bypass Control Solenoid. Once this was restored the misfire indications went away.
