Do I have a vacuum leak?
My truck has been acting totally f'd up at cold start. It stubmles and sounds like I have a big cam and almost stalls. Watching the boost gauge, it is all over the place from vac 25 to 10. Can't figure out what's going on. If I just let it idle for a few minutes it's fine, but, embarrassing when I start it and it almost stalls or actually does stall. it smells funky too. and i keep getting p0172 0175 codes. What the hell? Once I start driving it's fine after a few minutes.
