You have a misfire I'm 90% certain. Have a scan done for stored dtcs. If none are there. Have a good mechanic run a diagnostic.

Maybe a tune up? maybe some maintenance- I have nightmares like this- for some reason I own a hummer and it starts breaking down- yikes! then I wake up-

Your mil lamp is on. Scan it first. Don't buy un neccessary parts. What if u only need one plug wire. Please listen before u spend money
