st...st...studdering
Wondering if anyone has any thoughts on this new problem. About 2,500 miles ago, I replaced both my turbos on a 2000 A6 2.7t. After many trips back and fourth to the shop, they finally had it all put back together correctly. Everythings been fine untill I decided to change oil viscosities from 5w30 mobil 1 to 0w40. I have always used Chevron 93 octane and the last time I filled up I added fuel injector cleaner. Last night I noticed under moderate acceleration the car studders quite a bit. I just test drove it again tonight with the same results. While just cruising or idling its seems fine. It also seems fine when I mash it to the floor. It almost feels like a fuel delivery thing. Sometimes it seems like it is confused about which gear to be in too. Any ideas?
