Hi, My name is Jay

The code P0128 is for the thermostat may be stuck open and engine takes too long to get to operating temperature. For the misfire codes do you get any misfires when driving? You may need to get a reprogram of the PCM following this tech bulletin here.!ArGz65GfcqjYohZxU-XL1CdZdDMe
