CIS or CIS-E?

Can anyone tell me how to tell if I have CIS or CIS-E FI system? It's in a 1984 Coupe GT, with an automatic trans. I just got it and the gas cap was off. I was told by the previous owner that it has been gone for a couple years....any precautions I need to take before starting it? How should I flush the system? What is the best stuff to use when I do? Thanks, Josh

A CIS-E fuel distributor (by the air cleaner) will have an
electronically contrilled pressure regulator bolted to its
side... see link: (4 cyl example shown)

Post a picture of your engine bay and I'm sure someone will
be able to tell what you have under the hood.

It does have that electrical connector, making it the CIS-E variant. Thanks, Josh
