Here is the definition of the code in GM manual:
P0128 - Coolant Thermostat Below Thermostat Regulating Temperature, this indicates the engine is running cold, u need a thermostat

p303 is a cylinder 3 missfire I woul first check the coil and then the ingnition module, Then if this dont work you could have a bad injector. If after testing and still no fix you should check the compression in that cyl.

First, if you have access to a scan tool, check the reading of the coolant
sensor. Does it read a logical number? If so, the problem is likely intermittent.
Perform a "wiggle" test by wiggling the connector and harness to the
sensor while watching the reading on the scan tool. Watch for any drop-outs.
Drop-outs would indicate a bad connection. If the scan tool reads an illogical
temperature, check the resistance of the temperature sensor. If it is out of
specs, replace it. If it is in specifications, unplug the sensor and, using
a fused jumper wire, jumper the two terminals of the connector together. The
temperature reading should now be maxed out to above 250 degrees F. If not,
there is likely a problem with the ground circuit or voltage supply.
Check for 5 volts reference voltage at the connector. Also check for ground presence at the connector. If you do not have 5V ref. and/or ground continuity, check for these back at the PCM connector. If you have these at the PCM connector, then repair open or short between the PCM and the sensor. If you do not, remove the offending wire from the PCM and then check for proper voltage at the PCM pin. If it's present now, repair short on the circuit. If it isn't present after removing the wire and checking the pin, replace PCM

The following are malfunctions that could cause a rich condition:
^ Fuel pressure too high. Perform fuel pressure test.
^ Leaking fuel injector(s). - Perform pressure leak down test.
^ Vacuum leak around the MAP sensor grommet.
^ Oxygen sensor contamination.
^ Restricted exhaust or air intake.
^ Fuel Vapor Canister saturated with fuel.
IMPORTANT: If the front oxygen reading voltage is above 600 mV and the rear HO2S is above 600 mV all the time, the O2 sensors are probably not
