1990 Sunbird Le engine stalls when under losd unless I pump the gas.

What is your question?

I'm trying to find out what might cause the fuel injector in the throttle body to not give enough fuel occasionally when the engine is under load. Feathering the gas will keep it going sometime so I think it's fuel-related. Is there a fuel filter in the throttle body under the fuel injector maybe clogged? Vacuum hoses look fine. Does it have a ECR valve?

What is an 'ECR valve? TEST fuel PRESSURE with a gauge , and if it's easier , put on a new filter anyway. IF you change the fuel filter and the problem is still there , you haven't really hurt anything.
