So make sure to take a look at your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Infiniti G to your garage area.
  • EGR valve: The EGR valve has the benefit that it is generally easy to access and simple to disassemble/clean. You can always examine it and clean it, for this see our article on cleaning the EGR valve of an Infiniti G.
  • Injectors: Injectors are very sensitive parts and a few harmful particles may be enough to disrupt their performance. 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, only change it. A fuel filter doesn’t clean itself, so if it is clogged you will just have to replace it with a new one.
