Ok so I purchased a new oil sensor and fitted it this afternoon. Was working fine, then it stopped completely, and now it's working again. Oil pressure is reading low but seeing as this has not worked before I'm not sure what could be the problem.
I also purchased a low temp rad switch and fitted it, to find the one that I took out was exactly the same 68 degrees sensor. The fan is still coming in at 3/4 and I was expecting this to be much lower. What could the problem be.
Finally It gets up to speed just fine but at 90mph it's like hitting a brick wall and the car does not gain hardly any more speed!!!! my old 5 cruised at that speed standard.
Need as much help as I can get.
