well got it running .... Sorta .... When excwelerate or under load check 
engine light comes on and is some misfire diag  code is 2322 witch is 
"inlet air temp opn or short defective sensor or wireing."

My main question is where is the sensor located and can it cause this 
problem  .. no mater if it dont it must have somthing wrong i just need 
to find it.
