the starter was changed but now the car runs at a very high idle.
after changing the starter,why would the car run in a high idle?
on 2004 Acura TSX
i assume you disconnected the battery to install the starter, if so then ecm has lost base learned values. drive vehicle 10-15 minutes in stop and go traffic and it should relearn. if not then a trip to your local mechanic will be in order
