2010 corolla S low/rough idle

Asked by Earnest Aug 11, 2017 at 09:05 AM about the 2010 Toyota Corolla S

Question type: Maintenance & Repair

I changed the alternator in the car yesterday, and
for some reason after reconnecting the battery and
buttoning everything up it now has a rough idle.
Does anyone have any idea where to start first?

Perhaps you left something "unbuttoned". Go back over your work.
