i have a 2003 trailblazer ive done a transmission flush and and change. It has 61,000 miles should i change the fuel filter too? also shouldi change the pcv valve and the distriburator and rotor? I dont know alot about cars but i do know the basics of changing things that need to be changed, so i could really use anybodys help thank you.

 

If you have the new style Trailblazer, not the Blazer Trailblazer, then you do not have a cap, and rotor. Yes you should change the fuel filter, that should be done every 12-20,000 miles. Also the pcv valve is not a bad idea either, just get one from the dealer though.
