Okay guys, i HAVE LOOKED ALL OVER AND HAVE DONE RESEARCH AND I STILL CANNOT FIND WHAT IS GOING ON!!!! so i just swapped a built motor into my 90 talon. The wire harness is a 90 converted to a 91.. the previous owner did it. so heres my problem. i put in ecm link and when i first start up my car its starts really hard, and when it gets to running, after about a minute ecm link tells me the temp is like 300 degrees...but the motor is clearly not that hot. it is also throwing 0021 code. my wideband tells me it runs to about 13..1ish on the rich side at idle. im at a total loss. any help would be much appreciated!
