Cold start in the morning like normal for about 10 seconds then it stalled. Turned it over a few more times with instant turn offs. I tried one last thing and put it in first and gave it some gas, it stayed on but with crazy rough idle until it warms up. It starts like normal when the engine is warmed up. I cant build boost past 3lbs either. stage 2 apr
Ive also noticed my vacuum pressure changed from -22 up to -24 (-22 being normal) ive never seen it go -24 since i have owned the car.
