[MikeLV]

Got a tune up, new Plugs, wires, rotors, fuel injectors, cabin and engine air filter., and still its just going through gas alot faster than it should, any ideas on how to ID and fix the cause?

What do you average for a full tank?

It's summer.. so, you will pushing your Corolla harder... AC on..

rotate your tires and make your not haul heavy stuff in your Corolla

Get a OBD scanner and scan for codes...

My '05 sits on about 350 miles gone before I refill with gas. And I could still drive for a considerable amount more but don't want to run her dry.

FinalGear has a great point on the OBD scanner. Is your check engine light on by chance?..
