is there a possibility of the car getting too hot from the iat running it lean because of heat soak and causing the voltage of the ect to be thrown past its limit and trip a code? becuase the code still hasn't appeared again. i still have my 3 emissions codes and nothing else.

im getting between 12-14 mpg ranging from heavy to normal driving. and my engine is pretty much stock. as far as i know it should be getting 16+ in the city and 24+ highway
