I've got an 86 Iroc, 305 TPI and until yesterday, couldn't get any spark. Now I've fixed that an she starts, but doesn't like to do anything but idle. I can get it to wind up a little if i feather the throttle a whole bunch. I did notice when I am feathering it up there, my timing is all over the place. Any suggestions would help as I'm new to this whole "fuel injection" thing. If it doesn't work soon I'm throwing a quadrajet on the damn thing.
