dont' see anything wrong with my bad gas mileage on the last few tanks,
loss of power, etc.... and the 850rpms and idle is not up normal according to the service manager.............even thought the manual says, 650rpm is what is should be ...

and any problems I might have had, they blamed on the oil, because I was 1/2 a quart low....... only half of a quart.................

don't know if I should take my car to that dealer anymore.

That sucks...

Are you sure it's supposed to idle at 650 though? My G35 has never idled that low. In the morning it idles at like 1200rpm for a few minutes, than drops to 800 or so.... I forgot to plug an OBD2 scanner into my G35 to get the exact numbers...

But I've had similar problems with my other car. I removed the fuel rails, swapped injectors on two cylinders, cleaned the injectors, and reseated them. Then I restarted the car, expecting the massive misfires to switch cylinders... It stopped misfiring all-together

I suppose I should be happy, but I really didn't do anything... And I don't want to drive to work, and have the engine decide to go south on me in the middle of the freeway.
