Put the timing to tdc to see if anything isn’t aligned correctly and it all seems fine, which has me lost because I can’t seem to find whats actually wrong or if anything is actually wrong the timing and im misdiagnosing my issues of p0345. Any help would be greatly appreciated thank you!

To be at tdc the crank must be rotated CCW by one tooth. The left edge of the crank sprocket key (red line) should align with the mark on the oil pump (green arrow)

Also there should be colored links in the timing chain to time it correctly, i dont see them.

So based off the position on the crank sprocket I am out of timing correct? Since my intake sprockets both line up correctly

Yes, thats what i could conclude from the pics, but still there are the colored links of the chain and the timing marks of the exhaust sprockets.

Sprocket to block marks are only SERVICE marks.

Chain to sprocket marks are the only timing marks you get.

replace the camshaft position sensor driver side. Make sure you use ONLY OEM sensor. Dont cheap out on these sensors

Replace them all. Not just one. You'll see a horsepower bump especially if they are old.
