The problem went away for quite awhile actually but reared it ugly head again today.
Here are the 5 codes it threw today, including once again P0173.
P0115 Engine Coolant Temperature Circuit Malfunction
P0173 Fuel Trim Malfunction (Bank 2)
P0300 Random/Multiple Cylinder Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0304 Cylinder 4 Misfire Detected
Anybody got a single fix answer? Would changing plugs fix these? The coolant one throws me for a loop. Usually it read just above 80C and now today it was barely over 60C completely warmed up. But it is only 7°F outside today.
HELP please.

Two things that have to be brought to your attention. First is, if you have a continuing problem do not start a new thread. What you should do is revive the old one and post the new information. This way everyone knows what occurred before. Second is, you should not have cleared the original codes when this problem started in Dec., without posting the code numbers. Clearing these codes does not fix the problem. It just extinguishes the light on the dash.
Code P0115 is for a Coolant Temp. Sensor malfunction and at the least you should start there. If you never disconnected the plug from the sensor, then the logical move would be to take an ohm reading from the sensor. Of course you will need an ohm meter, and with the engine cold, disconnect the plug from the sensor and take an ohm reading off the two prongs on the sensor. Reconnect the plug and start the engine and bring it up to normal operating temp., shut off the eng., remove the plug once again and take another ohm reading. Both readings should be close to those readings listed in the below data.
