1999 Mercury Marquis Repair Question
Grand - intake manifold
This was a very common problem with this series of marquis. I believe it was made out of plastic if I remember right and the aftermarket one was of aluminum. It was poor design. I have a 1998 and replaced my intake manifold. I purchased an aftermarket one off ebay for $150 - $200. A friend of mine put it in for me took about 2-3 hours. So I would call around ask for quotes on how much to replace it for your year make model if YOU supply them with the part. I would say 3 hours labor @ 60 - 70 an hour is reasonable.
