What does GDI stand for

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! GDI stands for **Gasoline Direct Injection**, a system that injects fuel directly into the combustion chamber for better efficiency and power. The "GDI service recommendation" likely involves cleaning carbon buildup on the intake valves—a common issue with GDI engines. Since fuel doesn’t wash over the valves like in port-injected engines, deposits can accumulate and cause performance issues. Think of it as giving your engine a much-needed detox. Follow up on that recommendation—it’ll save headaches down the road!
