mccorry Posted September 11, 2007 Share Posted September 11, 2007 System too rich (Bank 1). Possibly a stuck injector, a dirty MAF, a bad O2 sensor..... Link to comment Share on other sites More sharing options...

rc0032 Posted September 11, 2007 Share Posted September 11, 2007 System too rich (Bank 1). No thats p0173. p0172 is to lean (Bank 1) The bank part adds no value and if you have checked the exhaust. I would start with boost tubes, the blue T etc. Link to comment Share on other sites More sharing options...

papa g Posted May 19, 2010 Share Posted May 19, 2010 Threw this code today. IAT was reading -40F on an almost 90 degree day. Car has been stumbling a bit here and there and today is was starting really rough. Cleaned the MAF/IAT and put it back in. Cleared code, started her up and she runs very nice now. BE committed to DO what it takes to HAVE more of what you want in your life!!! Link to comment Share on other sites More sharing options...
Leonardo Posted November 15, 2011 Share Posted November 15, 2011 Came up today for me, checked MAF and it was covered in gunk (Zero/Sport unoiled air filter in stock box) so it might be time to change filter. Cleaned MAF and will test drive later. Link to comment Share on other sites More sharing options...
JrBully Posted November 17, 2011 Share Posted November 17, 2011 My car just through the same code on the way home tonight. The only difference was that I was on the highway with my cruise control set. Hopefully it's not a stuck injector. I looked over all of my tubing and clamps going to my FMIC. Everything was tight and I clean the MAS sensor. Link to comment Share on other sites More sharing options...
jaxx4k Posted August 9, 2012 Share Posted August 9, 2012 how to test injectors if is a stuck inj.? Link to comment Share on other sites More sharing options...
Zac88 Posted July 10, 2014 Share Posted July 10, 2014 Every few weeks this code pops up on mine and goes away after a day or so. Might just be a little post MAF leak im thinking. Ill try cleaning my MAF tonight. Link to comment Share on other sites More sharing options...
SpecBlitzed Posted May 20, 2017 Share Posted May 20, 2017 P0172. Installed a aftermarket BOV and seemed to hold more boost. Intercooler was starting to split open near the turbo outlet. Installed the stock bov and squeezed the IC back together with some pliers. Don't install a bov unless you got plans for a tune. They do hold more boost and will cause problems. Seemed to fix my issue and car runs fine again Link to comment Share on other sites More sharing options...
subiegirlxlgt Posted January 30, 2018 Share Posted January 30, 2018 I had this just happen to me, seems it was just a dirty maf sensor Link to comment Share on other sites More sharing options...
