    What is wrong when my Check Engine light pops on and traction control light and it rumbling and jerking. Then when you turn it off and try to turn it back on and it does want to start. Then you wait and it turns over sounding ruff.

    This relates to the throttle body and/or its connector. This is a rather common problem that is quite well known. What happens is the connector — and sensors — for the throttle body pick up on the fault as there is more than a little feedback heading toward the connector, even as it is sending information to the Engine Control Module.

    You can tell there’s a throttle body problem by the fact that the engine runs rough and there’s a lack of power. It’s just what you described in your note.

    There are two potential fixes for this problem. The first is the easiest and least expensive, while the second is much more expensive.

    The First fix involves replacing the throttle body connector. Like the throttle body, if this particular connector goes bad, then there’s a problem and, again, its just what you describe.

    If this fails to address the problem, you will have to replace the throttle body itself. This should clear up the problem and your Malibu should run quite smoothly afterward.

    The cost is between $400 and $500.
