1990 caprice question

where is the intake air temp sensor located? also my front passenger tire leans inward would anyone know the cause of this?

If I'm not mistaken, the air temp sensor is located under the air cleaner. As for the tire leaning inward, your camber and/or caster is off and is affecting your wheel alignment. First thing I would check is to see if the shims fell out of the upper control arm. I have to ask though, if you hit or ran over anything real hard on that side. How long has it been this way?
