Need help diagnosing my LT1 ( San Diego)

[El Super Kevbot]

Im having ignition problems. Its just running rough. It been starting and driving fine, no major problems, just rough, down on power, and misses up top. I got new Delco wires and plugs ready to go in and a new coil and fuel filter. After that, I don't want to throw any more money at guesses.

If you have an obd1 scanner, that would help out too. Anyone kind enough to help a brutha out?

Thanks guys.

You can do the paperclip thing to the OBD1 port which is the lower right hand 2 connections on the port and it will spit out codes but it will only give a general idea of where to look.

Have you checked fuel pressure?

Only if it's a 93 F car or 92-93 Y car. The 94-95's with the flashable PCM did't have this capability.
