Codes P0171 and P0174
I am getting these codes on my car now,
Bank one is lean Bank two is rich I have checked all the vacuum lines from the back right of the engine to the front left as well as the one one the right front to left front of the throttle body. I start the engine let it run then unplug the MAF and im not getting any change in the engine at all, although i do get a service stabilitrack message on the DIC. I am completely confused on this and any help would be appreciated

He doesnt have a catch can. We checked his CAI to make sure all was tight nothing letting air in around the maf. All of his PCV inlets are plumbed correctly. throttle body is not loose.
User sees no change in performance ( not great running right now ) with the maf plugged in and the maf unplugged. User sees no change in driveability with it completely unplugged. can a loose primary 02 sensor cause those codes? JEFF: • Clean the MAF sensor. take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling • Inspect all vacuum and PCV hoses for cracks, breaks, connection. ( DONE ) • Inspect all hoses and connections in the air intake system ( DONE ) • Inspect and/or test the intake manifold gaskets for leakage especialy the Driver side. ( NOT DONE ) • Check for a dirty fuel filter and proper fuel pressure ( NOT DONE ) • Do the #5 and #20 FUSE PULL Overnight ( NOT DONE ) • Check Oil Filler Cap to make sure it is tight and secure, Check Fuel Filler Cap also ( clean them and the inlets with a rag ) • Replace front 02 sensors with new. • Check for header gasket leaks exhaust leaks • Run some seafoam ( 2 cans in a tank of fuel, you can get at autozone etc ) • Trade in for Chevy SS Sedan and to hell with it. LOL
