I have a 1994 xj12. When I bought it it wasn't running. The previous owner had the fuel rail apart and I put it back together but there are 2 vacuum ports under the leftside intake manifold that were sucking air. I capped them off but I'm wondering if they are suposed to be hooked up to something. Does anyone know what they are for?

Hi every one! I just purchased a 94 xj12. I had to work on it to get it to run, and thankfully it's finally on the road again. I must say that it's a joy to drive and I've decided to take on the task of restoring her back to original. That means I'll be spending time on forums and asking questions so any help from you Jag gurus will be greatly appreciated!
