Unscrew and unplug the two front o2 sensors. Try running it. Is it any better?
The bank 1 and 2 sensor1. The ones closest to the engine. Remove them and run it. How does it do?
I cant tell from here. Ill opt out and see if another expert will help out.
Different expert here.
Ok, causes of bogging down coupled with rotten egg smell are very few - catalytic converter failing, very poor quality fuel, fuel pressure regulator.
Crank engine over a couple of times and then remove the vacuum hose to the fuel pressure regulator - if fuel comes out of the vacuum hose or vacuum hose port on the regulator, replace it
Ok, if you have a fuel pressure gage, check the fuel pressure and let me know what it is with key on and engine off, as well as at idle
Would be nice to see the pressure at idle. With engine on ignition on, it is about 5psi too high, which does indicating a binding valve in the fuel pressure regulator
Crank and cam sensors signals could cut off signal to coils but not injectors or fuel pump.
It sounds fuel related and we need that pressure to see where we need to go with this
