    The dash, interior and head lights flicker on a cold start. the idle also slightly fluctuates. once the car is warmed up, everthing is normal. any ideas, alternator, battery?

    I'm not an expert but it is cold, I know when my car starts on a cold day i need to let it warm up fully or it runs horrible. Squeky loud vanos, marbles in the motor, etc. once it is warmed up all sounds quiet and smooth. Do the lights dim while driving?

    So far it's sounding like an electrical system problem.

    Check your alternator charging voltage and battery condition. Make sure the battery is charging properly. If both the battery and the alternator are healthy, check the fuses, the main power relay(s), and the power distribution system as well as the cables.
