Try changing your o2 sensors and a new fuel filter.

I concur with IanH's numbers. Sounds like IS3Jay solved his problem although he hasn't reported back with his mileage.

BTW, I love this car. It get's reasonably good mileage, it looks great, and it has serious power when you need it. I just wish the trunk opening was a wee bit wider, but maybe that's a topic for another thread..

so, either your car is turbocharged or you have never been a car that actually has serious power...

OK. Serious power compared to my previous cars. I figure I'll gradually work my way up to a 5.0 liter by the time I'm 70. "Watch out you whipper snappers!"
