Default stumbling

ok maybe someone can point me in the right direction .
i put tranny ,comp, and wiring harness out of a 94 z28 in my 95 formula .
the car startes and idles fine but if you press the gas it stumbles up to about 3000 or so then it smooth out . from about 3000 to 5000 it revs smooth but it still revs slow .
the fans come on as soon as you start the car and the only way to get them to turn off is pull he relay , and the fuel guage goes up and down randimly . (way past f then down to 3/4 then back up again . to add insult to injury the car sounds like a 6 cyl .

The fans comming on right away tells you that you have tripped a trouble code. Get it scanned to see what the code is. was everything the same between the two cars? As far as gear ratio...the pcm may need to be reprogrammed.

yea, sounds like a computer problem, especially the fans because if the computer sees something wrong it kicks the fans on to make sure it doesnt overheat
