I have a 01 Monte carlo SS. My engine light is on and ABS brake lights are on, and Traction light is on as well. The engine light said I needed a sensor. But this morning out of no where the car knocks slightly when I accelerate from a full stop. It knocks at the number 2 on the idle. What can this be?
