ok ran my husband's coder on my cougar and it came up with the fuel rail pressure sensor which I haven't been able to find nor any youtubes for the right engine/year/car to figure it out on my own. this last time I ran it about a week ago due to another odd sound when my son was driving it it came up with the code P1518 OBD trouble code. Looked up the code and it is talking about the intake manifold runner control conditions and after talking to my brother he said that it was prolly a loose wire or something. I'm trying to teach my son how to work on this car as it is going to be his daily driver but both my brother and I are at a loss currently and would love any sort of help we can get!!
