Alternator replacement, something to read about
Check engine lights can be triggered by such minor issues as a loose gas cap, bad spark plug wires or engine wetness. If your light signals a non emergency issue, check your gas cap and check your engine for wetness before going to the shop. Engines like to misfire if spark plug wires wear out, so give them a look as well. You may need only a simple wire replacement to make things right again. When you first go in to the shop, your certified repair technician will perform a scan test for stored trouble codes and test your sensors and components to eliminate possible sources of the problem.
