P7400 doesn't exist...can you recheck it?

Sounds like maybe something in the air intake system - too much air or not enough fuel? Could have an engine misfire?
I would recommend having the car checked out in full, as you just acquired it.
you know any place where i can take to check it beside dealer please kindly help me out to find the repair shop in my area yes it's the engine has misfire problem too the code is P1700 Also they give me 5 or 6 code i'll write it's down for you in the morning
