O.K. So it has been a week or two since my original post. My SECOND tank of gas ran to 380 miles; an increase of 100 miles.
I checked my spark plugs this weekend, and set them all to .041. The specs are .039 to .043 so, they are all smack in the middle. Only one was off and it was set a hair to large (.045 or so). I believe the 3rd tank is half way done so, I will see how it goes and keep you all posted. The timing gun seems like a great idea but I would rather save the cash if everything is where it needs to be.

I think your math was off when calculating your first MPG.

i did a tune up, plugs r ok, engine idles perfectly... but still bad fuel economy....so then i took it to the agent plugged the diagnostic tool & did a checkup....
The guy who did the checkup said the Fuel Injectors are open (when idling) for 3.4 to 3.5ms and it should be around 2.6 to 2.8.... is this normal ???
