When I got my car back with brand new fuel injectors from my mechanic, the car drove like it's old turbo self. The very next day, the car starts up, and puffs white smoke like crazy. After three weeks in the shop, they came to the conclusion that my piston rings have totally crapped out. I pulled my car out of there that instant. For now it's being garaged until I pull it and have my local speed shop rebuild the engine. Until then, I can only dream.
