I have a 04 neon 2.0. when it is cold outside say 35 degrees or so upon 1st start up the oil light comes on shut it off immediately then restart nothing only happens on first start up when around freezing. As long as it is say above 40 it is fine. What is up???????? Just a sending unit you think?

 

kinda hard to understand what your saying?????oil light will come on till proper oil pressure is built up , when its really cold out oil is thicker and takes longer to build pressure .
