Idle issues
So, I changed my maf sensor the other day. The car starts and idles fine for a few mins then rpms seem to drop and car dies. It doesn't matter if the engine is cold or at operating temp. Just seems odd that it holds perfect idle for up to 5 mins then it starts to act up. Also if I rev the engine past 2k rpm and let it fall back to idle it dies every time. I tried idle relearn process, maybe did it wrong. Any ideas?

I did carefully clean the sensor with crc maf cleaner, making sure not to touch any part of it with the spray straw. I suppose I could swap it out with my wife's 01 max. See if it fixes the problem. The new one I bought was the cheap AutoZone part. Possibly defective right outta the box. I'll let you know if it changes anything. Thanks for the reply though.

Most people agree the aftermarket MAFs are junk. You can buy just the sensor (Delphi iirc) off amazon for about $100. Be advised I ordered it twice and got the wrong part both times.
Since you have easy access to another one that is known to work take advantage and swap it out. Takes minutes.

Idle when cold is just barely over 1000rpm, maybe 1100. After 4 minutes or when warm it's right at 700rpm. It doesn't bounce or fluctuate at all, very smooth. Just looses rpms after a few minutes of running at operating temp.
