Tighten up Tilt column links;

On C/K trucks in 1995 they went to a “new” style column.

If your truck is a 1994 or older the following information should help.

Here are some steering column sites with photos that tell how to repair loose tilt columns. The photos should be helpful.

Looks like on this site he did the quick fix and did not take it apart far enough to tighten all four fasteners.

This is gonna be a great help to those who seek help, without asking "where, who, etc.," before doing a search for the help they need. There's a lot of information on here that people can access, if they will just take the time to utilize the already available resources.

Cleaning evap core for better a/c function

Edit: Also wanted to say that an 88-98 FAQ section is a terrific idea -- it seems like every day there's somebody with EGR/IAC/ECTsensor problems. The FAQ section should be subtitled "Is your truck running weird? Check here first!"
