My check engine light is on and has been for about 4 months but the past week and a half the traction control is being turn off when I run at highway speeds. If I turn the car off and restart the traction control light turns off until back to highway speeds. If I don't turn off and keep running with traction control light on at lower speed the car seems to jerk a little bit. I took to auto zone and the ran quick diagnostics test and I got 4 codes. The 4 codes are C0561 P0101 P0300 and P0411. What can I do to fix this so he codes no longer appear and check engine light is turned off.

C0561 = System disabled information stored. This is not the main problem and would not appear once the main fault is rectified.

P0101 = Mass Air Flow sensor performance. Check the air hoses for leaks (cracks etc) Have the MAF cleaned.

P0300 = Random Misfiring detected. Check the spark plugs and related components. Have the fuel pressure tested.

P0411 = Secondary Air Injection System incorrect air flow detected. Could be related to P0101 and might require the throttle body to be cleaned.
