2000 Lincoln LS 5 speed misfire

I have a 2000 LS 5 speed and I am trying to figure out if I am getting a good deal on a repair. Most of my Lincoln repairs have been very expensive. I just replaced the clutch for $788.21. I just had him try to figure out why it is cutting out so much and the engine light is on. It is coding "running lean" and he tells me that I need a new intake manifold gasket and new plugs. He told me it would run $548 with shipping costs for parts and labor. Are there any questions I should ask him? Is this a reasonable price? I also want to be sure that I am getting a straight story about the plug that is hard to get to and that you have to remove the manifold to fix. Vic

Welcome to the forum!

Leaking spark plug well gaskets are very common on the first generation of LS (try searching the forum for details). Intake manifold gaskets, not so much. However, if you truly are getting a code of "running lean" then the manifold gasket or some other leak is likely the cause as a leaking spark plug well seal would more likely cause a rich condition.

You'd certainly want to ask him if he'll check the plugs for wear and coils for evidence of oil leaking since someone would have to take the manifold off to check half of the plugs anyway.

The job really isn't as bad as it looks. If you or a friend is pretty good with tools and cars, they probably need not be too worried about tackling this and saving you some good money.
