P0299 code but I don’t have a turbo charger.

Hi this is Dusty, I'm one of the auto experts on RepairPal's Car Genius team. If your CR-V has a 2.4-liter engine, then that's for sure an odd code to have. That code wouldn't be if your CR-V has a 1.5-liter turbocharged engine, and it would explain the lack of acceleration you mentioned. An under-boost condition will exhibit the symptoms you mentioned because either the boost produced by the turbocharger is escaping the system by way of a leak somewhere or a valve being stuck open, or the turbocharger itself is failing to operate. Either way it should be diagnosed, driving a vehicle with poor acceleration is a risk to you and other motorists. An experienced, qualified technician will be able to make heads or tails of the situation and get your CR-V back on the road in full form.
