I had the same problem. Replaced everything else to no avail. Measured the injector resistance and found that 3 of the eight injectors were bad! Replaced the Multec injectors with Bosch and what a difference! The engine was starving for fuel before the injectors were changed.

I experienced a similar problem on my 85 and found that the plug wires were grounding.
the cure was keeping them from touching anything but the insulated holders. Hope this helps, Steve Meillier
