When I search for Code 34 or MAF sensor the result populated as inappropriate. The results are about off topic subjects. Anything but the search I requested. I tried your suggestion of tags which did not work. How may I search and produce the desired result.?

 

You could try using Google to search for certain keywords on a specific website. You can do this by adding site:thirdgen.org/forums behind the keywords and that will tell Google to search the site.

Google's main business is search. It's difficult to match the resources Google has. Therefore, there are cases where using Google's search engine is recommended. This is one of those cases as you're trying to search a 2-character/digit (34) and it's difficult to index 2-character/digit words.
