Ok i have a 1990 audi 200 quattro its a 2.2l inline 5 turbo im having a problem its not accelerating right its sputters a bit and the turbo doesnt kick in it just makes this blowing noise what cani do

Hello, I used to own a 1989 audi 200 turbo. These cars have a rather complicated fuel injection system called constant injection system (CIS 2). They can be difficult for most mechanics to figure out, unless they are already familiar with it. If you do bring it to a mechanic, try to find one that is familiar with these cars. And don't be afraid to get a second opinion. I had one mechanic claim that my car needed several thousand dollars worth of parts, another was able to fix it for under a hundred. The only suggestion I have is that it sounds like it is vacuum related. Good luck!

Sounds like a leak in the intake air tubing. Check for splits in any of the rubber hoses associated with the air intake.
