    This is likely indicating that a fault has been detected by the powertrain control module. You will need to have a repair shop check the diagnostic fault codes and then perform a diagnosis to see where the problem lies.

    I have an 06 premier w/4.6 engine. I had intermittent ABS lt with constant engine lt (U1900, B1676, u0101) with tranny shifting erratically. I replaced all spark plugs and the issues were fixed. Spark plugs ran $10 ea.
