91 Miata engine miss

91 Miata with 78000 miles misses when accelerating up to 3500 rpm. If engine load increases then miss returns. Checked plugs, wires, and vacuum leaks and all were good. Is this a fuel pressure problem? Injector maybe?

I don't know. What is the fuel pressure at? You need to check it with a gauge, pressing the middle of the valve to see if anything comes out means absolutely nothing at all. Have you checked for codes? Have you tried doing a coil output test yet?
