This can be many things, but it sounds like the fuel pump or crankshaft angle sensor is going bad but we should start by scanning for codes. Here is a guide to help

There is a possibility it is the EVAP purge valve so I would remove the vacuum line from it for now to see if it makes a difference.

Here is the location so you can run the test. Please go over this guide and get back to us.

Get a cheap OBD scanner and read the codes first†better to see if there’s an actual fault instead of randomly swapping parts.
