when driving in the mornings, it sounds like the engine is struggling. it maybe coming from the turbo area, it is almost like a vibration sound. but after driving for awhile it is gone. if i get on it hard, i dont hear it, it is just normal driving when it happens. i also let my car warmup for about ten minutes before i even drive it. my guess is that the turbo just needs to warmup, but please give me your opinions as i dont know a whole lot about turbo charged cars.

 

I live in an area that has roughly the same outdoor temps as where you live, and I start my car on cool mornings and let it idle for maybe 30 seconds before driving off. I take it kinda easy the first few miles, but the car warms up really fast when driving. I run
5w-30 Mobil 1 for the Texas "winter" months and haven't had any noise/vibration problems........are all your connections around your turbo and engine nice and tight?

i have checked the connections, but they seem to be good. i will check them again. this problem has only started since the cold weather arrived. it seems the only problems my car ever has is on the first start up of the day. i thought maybe i am driving to lightly in the morning, because it occurs at maybe 1/4 throttle or a little more. the cai maybe loose, i will check again.
