Hesitation
 

GIVE INFO ON THE ACRONYMS, I HAVE HESITATION IN MY 86 N/A LIKE IT MUCH, JUST FIXED THE IDLE PROBLEM BUT STILL HAVE THE HESITATION, PUT A LARGER GND CABLE TO THE ENGINE, NEED TO PUT MOR TO THE FIREWALL AND THE ECU, ANY MORE HELP WOULD HELP.

What is your question? What you typed doesn't make sense. And turn the caps lock off. What acronyms do you want to know? GND is ground N/A is Normal Aspiration, which means no forced induction (turbocharger, supercharer, NOS).

At 3800RPMs the ECU brings the secondary injector online, and they (along with the primary injectors) go into what is called batch fire. The ground wire for the fuel injector relay thingy is attached to the to of the engine block under all the emissions control crap. If it isn't secured tightly, or is old and crusty, the connection could be broken and the injector signal is lost.

Or, the other thing that happens at 3800 Rpms, is the opening of the auxilary ports. I don't know how much you know about how that works, but basically, you have a port for each rotor that is closed until 3800rpms. Then the air control valve opens and lets air from the air pump(the belt driven one) go through and this air pushes 2 actuators that are attached to the aux ports. The aux ports are just sleeves with a hole on one side and flat on the other (see pics below). When it rotates, the opening faces the rotor to allow more air in. More air requires more fuel, which is why the secondary injectors are supposed to come on. Sometimes the actuators stop working, or the carbon build up in the motor will gum up the rotating sleeves and stop them from turning.
