94 C280 Stumbling When Accelerating

Hello. I have been having a bit of trouble with my C280 lately. Sometimes, when trying to accelerate, the car suddenly stumbles and I swear I even hear a pop in the exhaust (excess fuel being dumped?). I pulled the following codes.

I've done some research, but have found conflicting answers. Could it just be bad gas? I only run 93. Any help would be appreciated.

Do the smoke test. These cars use copper plugs and they should be replaced every 20-30K miles. Old plugs cause all sorts of misfires. Bad eco rap wires need to be fixes too.
