Ok so I took it up to auto zone and got the code P0101. I drove home and it died on me for the first time ever Then I took off the MAF and cleaned it although it seemed to look brand new Then popped it on drove around for 5 minutes and my engine light shut off BUT When it idles it is a bit rough not as smooth as I would Like it to be. What are some ways I can clear up my cars idle? Thanks
