RE: [20v] ‘91 coupe hesitates on acceleration

Chris: 

Does this happen only under acceleration (while driving)?  Can you re-create the problem parked, by revving the engine? When the engine shuts off does it always happen at the same RPM? (Coil)

I’d like to provide a follow up to engine cutting off during acceleration problem. 

It only happens when warm. 
I changed the TPS and this did not help. 
Disconnecting the knock sensors did not help. 

Any other thoughts?

Thank you.

acceleration. It feels like the fuel cuts off for half a second while I am accelerating or sometimes even at idle. The car stalls during turns at times.
What could be causing this?
