The vacuum system also helps lower damaging emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, especially if they’re exposed to imposing heat or extreme freezing.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2019 Lexus GS 350’s exhaust system.
