Model: 2001 Hyundai Accent GL Fault Code: P0133 Posted: 2014-05-12 18:09

Hello, I own a 2001 Hyundai Accent and am currently experiencing multiple OBD-II diagnostic error codes: P0326, P0133, P1529, P0743, and P0722. After recently replacing the spark plugs, engine oil, and transmission fluid, I've noticed the vehicle is louder than before, occasionally shudders during acceleration and braking, and sometimes struggles to accelerate smoothly. What are the most effective troubleshooting steps or recommended repairs for these specific codes? Any insights from experienced owners or mechanics would be greatly appreciated.
