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

[Christopher Gharibo]

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.

What could be causing this?
