I bought a 1997 Buick Regal and as I was bringing it home from the owner the check engine light came on and hasn't went off sine the auto parts store said it was the EGR sensor I wanted to know what does this do? Also they told me I had to put platinum spark plugs in it or else it wouldn't run right is this correct?
