GLS Hybrid Fuel Injection Issue

I've seen similar issues on the GLS. Dirty injectors can definitely cause those symptoms. Have you tried using a fuel injector cleaner additive in your gasoline? Sometimes that can help dissolve minor deposits. It might be a worthwhile first step before committing to nozzle replacement.

Regarding the fuel injector cleaner, can you share the specific product you used? Also, what concentration of the additive to gasoline did you use?

I used a standard gasoline injector cleaner from a reputable brand, nothing too specialized. Followed the instructions on the bottle for dosage. Honestly, if the problem is significant, the cleaner might only offer temporary relief. Given the symptoms you describe, a proper cleaning or nozzle replacement at a workshop is probably necessary to restore performance and address emissions concerns.

Thanks for the advice. I took it to a professional. They confirmed the fuel injection system was contaminated and needed parts replaced. The car runs like new now, and gasoline consumption is back to normal. Thanks again.
