I DESPIRATELY NEED SOME HELP WITH TROUBLE CODES P0175 AND P0172 BANK 1 AND BANK 2 TO RICH. I AM OUT OF IDEAS. I HAVE CHECKED THE MASS AIR FLOW SENSOR, FUEL REGULATOR, AND FUEL INJECTORS AND CANT FIGURE OT WHY I AM GETTING THESE CODES.

 

I have the freeze data maybe you can make some since of it.
TROUBLE CODE PO175
ENG SPEED RPM 856
CALC LOAD % 29.4
COOLANT F 185
ST FTRM1 % -3.9
LT FTRM1 % -23.4
ST FTRM2 % -8.6
LT FTRM2 % -25.0
VEH SPEED MPH 28
FUEL SYS 1 CLSD

 

Just throwing out the possibility of one or more of the Oxygen sensors, How many miles on the vehicle?

 

150,000 miles. It isnt very likely for 2 to go out at the same time is it?

 

Wow, look at those long-term fuel trims.

Did you actually check the fuel pressure at the rail? 28-30PSI at idle, 38-40 under load (or at idle with the vacuum disconnected from the regulator).

 

I DONT HAVE A GUAGE I HAVE SOMEONE THAT IS GOING TO CHECK IT FOR ME ON SATURDAY.
