I know that P0172 is telling me 'System too rich bank1' and I have searched the web all over for a fix.

I have a 1999 Dodge Stratus with the 2.4 litre I4.

What repairs have you done to end the P0172 problem?

Thanks!

 

No one else has had any luck in fixing this problem either?

 

Have you checked your oxygen sensor? That's what the code is for It would be the oxygen sensor closest to the engine.
