I just fixed my code 14 and now this code 43 pops up. It doesnt come on right away, the car warms up and then pops on. Once the car is warm and I shut it off for a sec it sometimes wont come back on....

I am not running a cat, could it be the O2 sensor? isnt that code 1?

 

code 43 is fuel supply. I just had it on my car. Most of the time it's your o2 you need to change. i changed the o2 now i have no 43 anymore. also, make sure your injector clips are on good that will do it as well.
