Default Idling too high

Car starts but idling around 3000 rpm. Gives me code po102 saying there’s a sensor problem with the mass air flow

Here's a couple of things you can try or check that might help you. Confirm there is no vacuum leak anywhere which would cause a high idle.. Spray carb cleaner around the air intake system( intake gaskets, throttle body, vacuum lines) if the idle goes down address that first. You can remove and clean the MAF with air intake or Maf cleaner , might help if it's dirty and giving false readings. Can also unplug the Maf and see if the idle returns to normal. Good luck
