I just put a d16z6 in my 89 hatch, and I was throwing a few codes, but I have fixed all but my code 9 and when I press the gas all the way to the floor, the motor bogs down so much that the car slows down, and if I dont pull my foot from the floor at least slightly the motor will die out. All my vaccum lines appear to be in the right places and I dont think the code 9 would cause this problem...

It is like this, when I press the gas all the way to the floor, the motor will rev for about a second, and then bog down and die unless I take my foot off the gas by about half an inch. It makes no difference if I am moving or standing still. Has anybody had this problem before, and how did you fix it, or does anybody have any ideas??
