Hi,

I own a 2011 Lexus ISF, recently while driving, I noticed my check engine light came on and my traction control could not be turned on. (It was not off previously but the light indicating that it was off had been turned on.) I have a code reader and indicated that both system bank 1 and 2, were too rich. I checked the air filter and all of the fuses and yet nothing. I do not have any mufflers on the car and have not had a problem with it since I got the car about a year ago. The mixture is definitely, when the car is on and running it smells like pure gasoline and not normal exhaust fumes. If you any advice what to do please let me know.

What exactly were the DTCs?

The DTCs were P0172, P0175, and P0101. I’ve attached images of all the readings below.

Try cleaning your MAF first. The too rich DTCs are likely a result of the P0101 MAF problem. At the same time, check the MAF seal to the intake tube and ensure the MAF connector is in good shape.
