I'm attempting to pull excerpts and custom fields from specific posts, I've attempted using publish game titles and publish id however i am only succeeding in tugging each and every publish by using this query. For instance I've this code attempting to pull only the title for that publish with id 182

<?php $map = new WP_Query();
$map->query('post_id=182'); ?>
<?php while ($map->have_posts()) : $map->the_post(); ?
<?php the_title(); ?>
<?php endwhile; ?>

It pulls the title of each and every single publish that way and I am unable to work out how I will have multiple loops such as this each tugging content from only one specific publish. Can someone please explain where I went wrong?

Knowing the publish ID you'll be able to use get_post($post_id); like so

$post_id = 182;
$my_post = get_post($post_id);
$title = $my_post->post_title;
echo $title;
echo $my_post->post_content;

I have had luck with WP_query('p=182').
