Computer reprogram question
Quick question. Has anyone had the 21N08 reprogram done then undone? I had it done a while back, and not only did it not fix my cam phaser noise, it made my rough idle more rough. So, I had them reverse it when I had the cam phasers done. Since then, I lost between 4-5 MPG. Nothing else changed. I did recently replace the plugs and clean the MAP sensors to see if that would help, and no change. I have to call the dealer for something else, so looking for some input so it will at least look like I knoe WTF I'm talking about. Thanks
