Hello, my name is***** usually means the throttle body assembly has failed which is about a $400 repair at a shop. The first thing you need to do is have diagnostic codes checked which can be done at your local parts store for free. If car can not make it to parts store they will usually let you barrow scan tool with a deposit. Let me know what codes you are getting and I can give you a more definite answer. Thanks.
