My z28 got hot and the temp went into the red ! I checked the codes and this is what came up, p0141, p0160, p0300, p1441. It a 1997 z28 5.7 lt1. Does anyone know what i need to do to fix these codes? Thank you in advance for your help.

 

p0141 is oxygen sensor heater circuit malfunction (post-converter sensor left bank

p0160 is oxygen sensor circuit- no activity detected (post-converter sensor, right bank)

p0300 is engine misfire detected

i dont know what p1441 is, i have both the haynes and chilton manual and it isnt covered in either
