I have an 03 liberty 3.7l that will not run.. Had aP0112 code for iat..I replaced it with no luck..been troubleshooting and found that its reading over 300° is not faulty..I can pull it out of intake and leave plugged up and jeep will start and idle but is rough and iat reading sits around 102°.. if I try to install iat temps jumps above 300 and jeep shuts off.. seems like intake air temp is getting above 300° what could cause this..
