Unhappy New bigger throttle body 2006 4.7l now idles high..
Hi guys, I installed a bigger ported throttle body and now my engine idles at around 1100rpm. My IAC is perfectly fine. I tried with a brand new IAC and that didn't fix it. I'm wondering if there is a specific way I am supposed to calibrate this.

Thanks, Chris

Does it still idle that high after full warm-up?

Which TB is it? Fastman is known to sell ones where the plate is to small allowing air to pass by.

Has anyone else had to replace their FCM?
