MY 97 xj three morning ago, I started it up like always and it revved up to 2200 rpm or so and wouldn't idle down even with me maunally messing with the throttle arm on the intake. Now when it gets warm it will idle at stop by bounching around 200-300 rpm. Just a constant vroom vroom vroom type of deal. The check engine light came on yesterday so I am thinking a sensor but which one? Have any of you had this problem? map sensor? Thanks for any input
