Hi, welcome to just Answer. I’m Ron and I’ll be helping you today.
Before we get started though, Please understand that I don't know
your skill level or tools you have to assist us. Also understand that
I can't see, smell, hear, or touch the vehicle either, so patience is
appreciated. JA is a great Q/A site, but it does NOT replace a
repair shop.
My goal is to make you happy and get a great rating in return for
my time. Sometimes I have to give you bad news that I know you
didn’t want to hear, so please don’t shoot the messenger.

A bad mass ir flow sensor can cause this as well as bad O2 sensors.These parts are not cheap, so it would be best to attach a scan tool and check for codes and DATA related to these components I mentioned. A weak fuel pump can also cause this,so checking the fuel pressure is in order as well. Please keep me posted.

Thanks, Ron
