Stumped on MPG

[MDPuckett84]

Ok this is here because i cant reply to my other thread anymore,
http://www.explorerforum.com/forums/showthread.php?t=132395
basically i still dont know the problem, but im hoping this might help someone help me. I took my scanner and let it read each sensor for a few seconds and posted the results here . The first listing is the sensor readings, and the little table on the right relates rpm to gm/sec readings from the MAF. Hopefully someone can spot a problem from this.
Thanks,
Matthew

edit: btw, except for the part where i revved the engine in the table, all values are at idle

Ok I think i might be getting somewhere, I setup the data log and drove around some. When i started it up the calculated load average was 25% after that, it rarely ever went below 50%, even when sitting at a stop light. Infact in a few cases when sitting at a stop light it was at 60%. What sensors is this data pulled from?
Thanks
