I've gotten a Injen Cold air intake installed on my nissan sentra by a local autosports shop and now i have this check engine soon light on my dashboard. the people at the autosports shop claim that the check engine soon light kicked in when he removed the battery from the car to install the cold air intake and the light will go away after couple of start up's. is this true and is there another way of turning it off?? these ppl at the autosports shop are starting to piss me off.
