If it is running, I would not change parts just to change them. Injector failure is inevitable so change them. But I would try to ohm the plug wires, unless original appearance doesn't matter to you. Also read the threads ondiagnosing the coil packs. If you make wholesale changes, you may never identify the root cause. Change one thing at a time. Even if you change out a good part you can keep the known good parts as spares. You are in Chicago, no better place for a ZR-1. Plenty of help in that neck of the woods, and some real professionals.

Good Luck
David
