I called Josh @ Stillen and they said it was a vacuum leak or one of vacuum lines might be kinked. My mechanic went through the install and made sure no lines were leaking or kinked. So he resetted the code and the car idled normal again. Now i drove it for another thousand km and the engine light is back on and the car is idleing at 1K again.

Any ideas?

Thanks guys
