Hi guys,
So I have a 2012 Mustang gt.
It has : cai, off road x pipe, sct x4 tune
I purchased a bbk 85mm TB and installed it.
I did the bbk recommended re learn ( un plug battery, let it idle, turn AC on with idle etc )
The car will hold revs and at stops it will slowly rev itself to 2,000rpm and then after 20 seconds go down and idle at 1,000rpms. It doesn't matter how many times I've un plugged the battery and did the re learn it's the same thing. If I turn the car off sometimes once, sometimes I need to turn it on and off about 3 or 4 times, the idle will go to normal approx 750rpms and it will then drive normally. Initially it had no check engine lights , I gave up on it , I put stock TB in and car drives perfect. Now I decided to play with the TB again as I have a boss manifold to install shortly.
Anyways it's doing the same thing and today a check engine light came on for :
P0507 ( idle control system )
P1450 ( evap system )
Online I read to change the purge valve by the TB which I did but I still got code.
Fyi : check engine light would come on lately once every few days with the stock TB for the p1450. But I would clear it and it drives perfectly fine.
Any ideas ?
