The check engine light turned on, so i got the codes and it brought up " Lack of bank 1 02 transistioins- lean explanation. ECH detected bank 1 02 at its lean limit.
Probable causes
1. misfire bank 1.
2. Vacuum leak affecting bank 1 only.
3. Fuel injector problem bank 1.
4. Engine mechanical condition.

What i noticed was that the car sometimes feels like its about to die or cut out when its driving, what is the main problem and what all should i fix and what order?

First things first. Common issue - pump and or regulator. A gauge mounted on the drivers wiper will tell the take. Hook it up to the fuel rail bleed.
