Misfire during start and lean codes p1342 p1344 p0171 p0183

Just started getting these codes: p1342 p1344 p0171 p0183, the p13 codes are misfires on start in cylinder 1 and 2. The p0183 is a fuel control mixture lean (bank 1 sensor 1). P0171 is the infamous system too lean code (bank 1).



Here are the things I did on the car so far: Cooling overhaul, DISA replacement, new spark plugs, new idler and tensioner pulleys, and a steering guibo replacement.

I did notice when I was doing the guibo replacement that this hose was torn









What is that hose and could that be what is causing the lean codes and possibly the misfire? Is that the dipstick hose?
