I bought the Pro-Flow 70mm MAF used, along with my JRSC, cam gears, pulleys, 65mm TB, and injectors. When I had it all finally installed, I was having serious idle issues. It would just not hold an idle...Always stalling out. So I started Troubleshooting by first swapping the 70mm MAF with the stock one, and bam - perfect Idle. I reset my ECU and everything, so it's not that. do I have a bad MAF or what?
