Engine RPM's surge, engine shakes and bad poor throttle response

My car gets very poor gas mileage. ECM throws codes for MAF sensors (replaced.) It showed a high and low input on the obd scanner and upstream and down stream o2 sensor codes (not replaced). Doors lock and unlock rapidly and set alarms off. Engine rpm's surge and makes engine shake and vibrates whole car. Traction control light stays on it says service traction control the variable timing. Solenoid has been replaced. Also, sometimes when stopped at red light you press the accelerator and it dose not respond, the rpm's do not move or down it just keeps idling kind of like a bad TPS sensor. I need help so very badly to figure this one out. I am thinking it is either the BCM or ECM mabe even TPS. Spark plugs have been changed and I have got continuity through my plug wires.
