Suzuki SX4. Engine light.
I have a 2009 Suzuki SX4 hatchback. The check engine light came on. Garage said it is the catalytic converter. After a few days of driving, the light went out. Should I have someone else check it. Wouldn't the light stay on unless it is something like the gas cap? It will cost a lot of money if it is the converter so I want to be sure. Thanks for any help.
