W124, acceration problems

Hey folks, my 89 300te is experiencing very rough acceleration problems and will cut off if I punch the accelerator. The problem started the other day but it only occurs when the engine is to temperature (not overheating), it runs fine when cold. When this occurred the other day, upon trying to start it, the engine seemed to want to kick back and backfire through the intake like the timing was off. After some time (Probably after some cooling down), it started up and I was able to drive it, though it ran poorly, it still idles ok.

I replaced the fuel filter and the car has a new ovp relay. The fuel pump relay is fine.

I am new to the org. Any thoughts? Maybe the CPS or 02 sensor?
