Default Help...Sudden loss of fuel economy!

So i have recently had a sudden loss in fuel economy, i have an 03' 4.7 and it is sucking fuel like crazy. I usually can expect 300 miles or so to a tank and now i am at around 200. I have ran 2 tanks through, i have a k&n and thought that was dirty. It was but not too much and i gave it a good cleaning. Still having the problem though. Any ideas??!

I have heard maybe PCV valve, or 02 sensor? I have not cleaned the throttle body yet, and i am at 155,000 miles now.

Thanks folks... Brian
