Also I think 145 degrees Coolant temp is where the car goes from open loop to closed loop fueling. If its in open loop its not reading off the oxygen sensors. If the gauge is pegged at 160 and not moving its hard to tell what your ECT is reading
So you need to replace the thermostat or the Coolant temp sensor. Post a scan when you get to normal operating temps so we can see where your Injectors and pumps siting at
