car accelaration

Asked by Jan 30, 2017 at 02:12 PM about the 2004 Toyota Corolla CE

Question type: Maintenance & Repair

My car runs normally with CNG. But when put into octane, it doesn't accelarate. It jerks and tends to stop. But in CNG running smooth. I am puzzled.

As CNG is considered an low emission fuel the computer controls are very limited, so when you switch back to gasoline the system kicks back in, now if there is a problem with the engine management system then you will have running problems on gasoline and don't when you switch back to CNG. So it is going to have to be checked out by a tech that has experance with CNG/gasoline configuration.
