MAF not reading..4 other codes HELP!!!
MAF not reading..4 other codes HELP!!! I have an aggresive H/C setup, and since it has been getting hot here in Chicago the car has been acting weird. I am getting a bog off idle. When the car idles for like 1 min it goes extremely lean, it pegs my wide band. Then if I go to accelerate the car just bogs, there's no throttle response. . I am getting a MAF heater code, a TPS malfuction code, and both O2 sensor heater circuit codes.
Just wandering if something can be off in the tune. The Maf is locked at one reading it doesn't change. We tried 3 other Maf's, all do the same. It's like it running in safe/limp mode.
Vetern tuners please help..just wandering if it's a wire issue or a tuning issue.

My engine builder did my tune, he uses HP Tuners. He's good but he's better with a FAST system. I just never noticed this problem until the hot weather. I think it is just getting too lean at idle. Gonna check the fuses but I thought they were all ok.
Someone was also talking about closed/open loop, and I was wandering if a bad tune would cause it to stay in closed loop.
