Will Creating a Keyword specific Page to replace the Category Section page cause any harm to my website?

I am running a word press install for my blog and recently had 3 of my main keywords set as categories. I recently decided to create a static page for the keywords instead of having the category page showing all the posts within the category, and took it off the navigation bar.

I read about setting the categories to use NO index so the search engines can shine more importance on the new pages i created to really replace where the category was showing.

Can this have a negative effect on my rankings?

junk car removal nj is showing the category section, So i placed the no index on it. Will the search engines refresh the data and replace it with the new page I created?

There is no telling what they will do with the page you replaced it with but I would put my money on the new optimized page doing better than the category page ever did.  You should have more content value on the new page.  Category pages are often linked to so I would run a link report on the old URL and try to get some of those links to change the page they are linking to.

Since you are using WP, I would also consider adding a category specific loop on the page that took the category page. This would be a big help to users and show some good relevance to the search engines.
