More then likely this is a vacuum leak. Here is a guide that will help with figuring this out for sure:

If there is no vacuum leak then we need to monitor the fuel pressure and find out if that is correct as well.

I suspect this is an air issue which is why we lead with a vacuum leak but if both of these check out then we will need to know if there are codes.

If there are no codes then we need to move onto a possible mass air flow issue but we can get to that once we get through all this. Thanks
