Whats up guys i'm new to this site and i joined because recently i have been having issues with my 05 Impala LS. When i first turn it on in the morning the rpms start going up by them selves i recently had the Air Mass Flow Sensor replaced. Another thing too just about a week ago the abs, traction system, and check engine all turned on and have stayed on. If y'all could right down some suggestions it would be appreciated.
