Maintenance history on you vehicle is important here. For example, when were plugs and air filter changed? How many miles on vehicle?
That said, vacumn leaks can cause idle and power issues on gas vehicles. What does TDS mean? If a european Diesel, I personally am at a loss. Others would know more.
More information on the vehicle is helpful to narrow down the problem.
