I'm getting two codes they are P0190 which is FRP sensor signal low and P0172 which is system too rich Bank No.1.

Would the FRP sensor signal low cause my car to act like it's misfireing or bogging down?? If so or if not what would i need to do to fix that??

For the other code could that sensor low be why bank 1 is running rich??

Or could my tune be messed up?

 

How much is a new FRP sensor. Maybe it would be worth replacing.

You could also try cleaning your MAF "very carefully".

 

P0190 indicates a Vref problem in the wiring, sensor, or PCM (read more here).

Also, many of the possible reasons for P0172 are fuel system related (click here)--I'd replace the FRP 'twas me...
