Default 85 Crx bugging down

So I have an 85 Crx si that's fuel injected. The guy I bought it from Mickey moused the wiring. However up until the last couple weeks I have had no issues.. So let's start from the beginning. I had over heating issues. Figured out that there was a bunch of crud in the cooling system. Fixed. Now I'm having a fuel issue. Weather it's computer or mechanical I'm not sure yet. I've changed o2 sensor and fuel filter. Adjusted throttle. When I baby it everything is fine. When I floor it the car says no and Boggs down.

Any thoughts????

When it bogs does it backfire?

It did once but not since. And it was parked I was Reving the engine to check if the fuel filter fixed the problem. It did not

usually the first thing i think when it bogs down like that under load is insufficient fuel flow. with the new filter it could either be a pump that is clogged or not flowing well enough, or possibly really dirty injectors maybe....with the age of the car the pump is my suspect though.

really great looking crx...
