Terrible MPG's

Check the O2 sensor with a voltmeter (Someone can post up what it should read or you can get the specs) and make sure the hose to the MAP sensor isn't bad. Especially the hose going to the MAP sensor which seems to get clogged with crud, and throws off the readings, causing poor fuel economy. (a pin hole in that line will cause over fueling too)

what about a faulty temp sensor telling the computer to run it rich all the time?
