1987 D21 with Z24

I'm out here in Southern Utah and just bought this 1987 D21.I'm trying to figure out this TBI. The truck runs pretty good at cold start, but it starts running like crap after it's been running for a while. I feel like it's running too rich and I do not believe the fuel pressure regulator is leaking. Any advice on where I can get educated a little better? Or any ideas online? The truck is running this way. Thank you in advance
