I've read that the b18b1 is supposed to be 199 compression and the lowest it should be is between 135-150 mine is at 120 in all four could that be my issue?

Code 6 is ECT... Engine Coolant Temperature. It is a critical sensor and needs to be fixed. Remember that depending on what the value is that is being sent to the ECU, you could be WAY rich or WAY lean. Under normal ECT operation, the car will be rich when it is cold, and slowly lean out to normal fuel delivery once the car is warmed up to proper operating temperature. Fix it and see if the issues clear up.
