Question about Cars & Trucks
No, its better to just swap over all necessary components especially since your vehicle is categorized with EGR and may not pass emissions if you eliminate it.

if you look at the front of the motor you will notice one cyclinder is further forward then the other... that first cyclinder would be 1. i'm guessing the side opposite to cyclinder one would be bank two.

To trouble shoot your rotten egg smell... have you checked your coolant level. Usaully when you smell a rotten egg smell from the exhaust it indicates that your engine is ingesting coolant. Possible causes are: blown head gasket, cracked waterjackets in one or more cylinders, intake manifold cracked or leaking manifold gasket at the heads. My buddy and I just got done changing out his intake manifold along with waterpump gasket, cooler line O-rings and oil pan gasket. He was finding that he was slowly loosing coolant, but nothing on the ground. I went to his exhaust and smelled it as it was running and it smelled like rotten eggs. That told me that he was ingesting his coolant. We checked around the intake manifold (plentum) gaskets and could see that things were looking damp. My friend did some checking around at the dealer and he found out tha GM has a lawsuit against DexCool (orange coolant) because their product was eating away the seals and mixing with the oil. My friend is driving a 2002 GMC Seirra (96,000 mi - 2nd owner) with the 5.7 liter (Aluminum heads). We pressure tested the coolant system and found that some of the coolant was coming out around the water pump seal as well. GM said that his truck wasn't on the list yet, but it could make the list soon so he's instructed to keep in touch. We also noticed the O-ring on the cooler line showed signs of failing because of the white crusty stain that tracked down the base of the head to the manifold. During all of this his truck seemed to be running fine. Before things got worse we decided to pull the Plastic (on his engine) intake manifold to look at the clip-on style gaskets. They looked bad. They are made of a type of silicone rubber and they looked like they were chemically melted or just like they were getting mishapen (kind of wavey looking in area's). We went to ADVANCED AUTOPARTS store (where we have received years of outstanding advise and quality parts) and queried the parts specialist who told us to also (because it's plastic and there have been known problems with the OEM intake manifold) check with a straight edge, the levelness of the mating surface on the intake manifold (gaskets removed of course). Numbers 2 & 4 intake ports had about a 0.040" gap under the straight edge. Even the silicone style gaskets when compressed can't bridge that gap effectively while under pressure. We searched the intake for cracks as well and found none, but to correct the intake problem we had to order a new intake from ADVANCED AUTOPARTS STORE and the new OEM standard replacement comes with a solution to the known problem and had thicker mating surfaces and the gaskets were embedded in the new design. while having the water pump off, and the intake manifold off we took the oportunity at and changed out his timing chain and gears along with his oilpan gasket that came with the FRAM water pump gasket kit. After making sure that his timing chain sprokets where aligned we put everything back together but opted to change out the AC Delco plugs for NGK Irridiums and OMG... Brother, there was no more leaks, no more throttle hesitation which is standard with OEM plugs and the truck set you back IN YOUR SEAT. The backend got started to float from left to right a rolling start of about 15mph to get out ahead of traffic that was just leaving the light and because of the recommendation of the reps at ADVANCED the truck runs like a Raped Ape. I litterally found myself searching for a break pedal on the passenger floor. LOL My buddy said that truck has NEVER run like that in the all the years that he has owned it. It always ran very clean and nice, but HOLY COW!!! He was grinning like the little school boy that just got his first kiss out on the school playground by cute little Lisa. Best of all... No more leaks and no more rotten egg smell.
You may not have all of these things going on with yours or maybe you do, but to address the smell I would look the engine over and pressure test the engine cooling system and if you're using the Orange coolant, GET RID OF IT before you spend approx $800.00 like my buddy. The coolant could also be causing your rough running engine. Coolant will choke up a cylinder causing your vehicle to run rough or irratic. We did the work in 2 days taking our time and making it right and he hasn't been happier ever since.

SOURCE: EGR Valve, O2 Sensor
Absolutely a bad o2 sensor can cause problems with performance. If you replace one it is highly recommended to replace both or all four depending on your vehicle. If one o2 sensor is making your vehicle run rich you will burn more fuel and in return increase the amount of carbon or unburnt fuel if you will in your egr valve you could probably get away with cleaning it but I would recommend replacing it, it will save you from having to pull it off again. Check your catyletic converter because long exposure to carbon will mess it up.

the bank 2 sensor2 is used to check that your catylitic converter is working on that side of the exhaust. without seeing the car and doing sensor tests, it would be a gamble to say replace the sensor. so you can replace it and see what happens or take it to your favorite shop for further diagnosis
