Hello, I am going through map sensors about every 4 months on my 1994 eldo.
I just put one in yesterday and noticed everything in the intake/valley pan area is covered in oil, the map sensor was also covered in oil. Is this oil causing the map sensor failure and if it is, what could be causing the oil in the valley area?
OK Thanks! I was looking at the map sensor I took out, inside the tube there is a shiny area, it looks like about 1/4 of the shiny area is covered with dirt. could that be causing and intermittent MAP sensor problem?
