So my check engine light came on yesterday before that my car had been running okay besides that when I stop anywhere instead of my car going into autostop it would try to go into out stop then go down like it was going into autostop then it would try to stay back up and start making a click click noise repeatedly than it would just die. I notice it's only gets 20 miles to the gallon anymore and vibration has gotten worse.

First it sounds like the battery needs to be replaced, can I ask how old it is? I suspect the engine may have a camshaft timing problem (worn timing chain or broken guides), although we also need to investigate the fuel pressure issue.

P0017 — Crankshaft and Exhaust Camshaft Correlation

P0089 — Fuel Pressure Regulator Performance

The high-pressure fuel pump is driven by the camshaft, so I would investigate the timing problem before replacing the fuel pump. So, can you upload a short video of the engine running, I need to see if there is a slight rattle noise while idling, this will tell us the timing chain system is worn out or broken, we need to start there. This guide can help as well.

Okay yes I can add a video of the vehicle running..

Also so I am currently still driving this vehicle as its my only vehicle my check engine light has went off and came back on twice it also is throwing more codes which are P2228 and P0133 on top of the other two codes said in my main question?

Is it still okay to be driving this with it throwing these codes I know I have to keep my foot on gas and break at stops bc it will die if not bc for some reason it won't or can't go into auto stop without making a clicking noise and then just dieing.

I would not recommend driving it until the stalling problem has been diagnosed. Having to keep your foot on both the accelerator and brake to prevent the engine from dying is unsafe. The engine could stall unexpectedly in traffic, and you may have reduced power steering assistance or brake assistance if it shuts off.

P2228: Barometric pressure sensor circuit low. This can affect how the engine computer calculates engine load and fuel delivery.

P0133: Upstream oxygen sensor slow response. This can result from an aging oxygen sensor, but it can also be caused by incorrect fuel mixture, exhaust leaks, or other engine performance problems.

These are all signs you have an engine vacuum leak. Here is video and guide to help us fix it.

Yes it has good power that I can tell. And my check engine light has went back off again it's very weird bc when I check for codes with code reader after the engine light goes off nothing pops up. And even when I look for history of codes sometime they all show and other times none show I get very confused with it. I can send u videos of what Im talking about
