My sister has an 04 mazda 6 with a 2.3.When driving at a steady speed with or without the cruise the rpms will fluctuate, the when you let off the throttle and brake it keeps revving.I did some research and it seemed like the throttle body but I replace it and still have the same problem.There are no dtcs present.Thanks for any help.
