Just scanned car don't know what to make of data
 

Well, I've been burning a lot of fuel. Getting 14 mpg in the city and the highway, no matter how much throttle I'm using. So, I scanned it, and I don't know what to make of the data. My o2 volts were jumping all over the place. At idle from .2 to .6 and at revs they were jumping all over the place as well. I was getting a EGR error in the trouble codes. It seemed I was also getting lots of knock retard when I revved it up.

Would anyone be willing to have a look at some scans if possible? Just tell me what program you prefer them in, what I should do while scanning (Don't have a laptop, so I can't really drive, just sit there and idle/rev it up) And I'll get the logs posted asap.

Thanks
