Problem solved then. Pumping to just above the recommended, learning hypermiling technique. Seafoam, of course.

Good quality car. I got it only had less than 42k on it. Even tho its 3 years old, its still good car and nothing wrong with it.. yet.. was a lease car so i know the maitence was up keep on it. Tires on it still have that new tread pokers on it and brakes were just installed when i got it. Up keep is outstanding on this thing, minus the 25k years of miles that somebody put on it. Never had issues with chevys as i always had them, buick was my first car and it was a dump.. transmission kept slipping and costing me more than it was worth. Traded it for a chevy malibu till i got a HHR and been happy..

My wife had a 2000 Celica and every time the MAF got dirty it would hesitate when you pressed the gas until you let off and hit it again. Her gas mileage also went to crap.

dING WE HAVE A WINNER! Firestone took the air filter and spray some cleaner through the hose and it was dirty, and had a twig stuck in it half way in it. Not sure how that happen, but its fixed. I just ran premium one last time and seems to be back to normal. Who would thought a stick in side the MAF would cause a issue.. Thanks for the advice guys and gals.. and my tire pressures are back to normal 36lbs as they was running 30-32.
