Surging Idle
New to this forum !!! I have a 2004 sentra 1.8L. 102,000 miles. Warm engine at idle RPM drops 200 to 300 then returns to normal. Happens randomly. The MAF sensor was replaced 2 weeks ago due to no acceleration above 20 MPH. Any help appreciated Thanks !! Also checked codes have a P0171 lean bank 1 "Pending"

hi there,check the rubber intake boot between the air filter box and the throttle body,chances are it is torn open between the bellows.this causes an air leak that is not accounted for by the mass airflow sensor because the leak is after the air flow sensor.
