Engine oil overfill. My Camry dies after running for few seconds?

Camry 1987 3S-FE engine 220k Auto 2lt. EFI system. I overfilled with engine oil and the car smoked a lot. I drained the excess oil but now the engine stalls after running for few seconds. What could be wrong?

Two sensors are inside distributor.I couldn't see the O2 sensor and the PCV in this model.

The oil level before draining the excess oil was about 30mm above the upper level. On inspection I found no oil leak inside the distributor. Also I found the path in the throttle body where the hose coming from rocker cover is connected is blocked. Can this be the reason?

I also suspect the throttle position sensor and another sensor which I don't know the name, because the oil that splashed through the hose connecting the rocker cover and the throttle body could have done some damage.

I haven't inspected the condition of the TB yet. A sticker says the TB has been changed at 100k. All four spark plugs are firing and I could notice the fuel is under the right pressure.
