89 4wd 22re highr rpm misfire, replced, coil, ignitor, plugs, wires, and distributor, dist cap, and rotor. Keeps throwing an IGF code and has rondom but consistent misfire. Checked all groungs, even added 2. Ideas?

 

is it getting enough fuel?

 

We have tracked it back to the computer putting too much voltage to the igniter. Ordered one yesterday, be in on thursday. Let you know if it works.
