So, after replacing my EGR with a new one and new gasket, everything seemed to be fine. So after drving around for a few, I got a new code. And this is what I got from my scan tool
P0171 Fuel Trim too Lean (Bank 1)
So, Im getting to much air now? I just filled up with 94 octane (according to the gas station )

So, after reading some old posts with the same code thrown, I have come to realize it could be anything really. This has just started once I put my new EGR valve in, so I am getting better airflow most likely. I might try putting my maf screen back in and see what that does, since maybe the maf sensor is being tricked.

Well, I put the maf screen back in, no more code for fuel trim too lean (think it was a bad tank of gas) but I still got the error code for bad EGR. Do I need my tubes replaced as well, or is this a sign my upper intake is going? Im runnig easily within normal operating temperatures. Im just a little confused
