  • EGR valve: In truth this valve which controls the return of exhaust gases for pollution standards can become dirty and disturb the evacuation of exhaust gases which can trigger Lexus IS vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that regulating the fuel/air mixture flow may be dirty or damaged, which will bring out the wrong amount of mixture and thus prevent your engine block from working properly, it is even possible that one or more of your cylinders are not running effectively.
  • Fuel Filter: Like the injectors, if the filter is clogged it will not let the fuel pass effectively and therefore disturb the operation of your Lexus IS, up to the point of producing vibrations during acceleration.

So make sure take a look at your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Lexus IS to your mechanic.
  • EGR valve: The EGR valve has the advantage that it is quite often easy to access and simple to disassemble/clean. You can always take a look at it and clean it, for this see our article on cleaning the EGR valve of an Lexus IS.
  • Injectors: Injectors are very sensitive parts and a few impurities may be enough to disturb their operation. Use a fuel additive to simply clean the injectors, if this is not enough you will have to go to a specialist.
  • Fuel Filter: If it is the fuel filter, just replace it. A fuel filter doesn’t clean itself, so if it is clogged you will basically have to replace it with a new one.
