what i want you to do is drop your cat out the bottom. there are three nuts that hold it on both sides. take it for a quick rip its gonna be loud as **** but if it runs better thats your problem. it could easily be something in the fuel system too. filter, injector, regulator. LET us know how it goes, i feel useful if i actually help someone.

the ecu will store the code until 5 no code starts are performed, its how well the engine runs. the 43 code is the fuel system. i would start by replacing the fuel filter. usually the pump either works or doesnt. but i would check the fuel pressure with a guage at the banjo fitting...pressure should be 30 psi approximately. if you have bad fuel pressure than your pump is bad or the regulator is bad. if pressure is fine and you have changed the filter and the code is still on, then it may be an injector.
