very poor gas mileage HELP
hi guys i have a 2002 gs300 and it's gas mileage is soooo bad! i currently have 60k miles on it so everyting is basically a virgin, i do not understand why my gas mileage is so bad, i would drive for only 7 miles or so and i can see my gas gauge literally drop very noticeable. and short freeway drives would be worse. i just dont understand, can you guys help me? i always pump 91. and i dont drive harsh either, but i notice when i step on the gas, my car is hesitant to go there is a little lag where the front suspension would squat up and then go. thanks.

Check your air filter if its dirty replace it, clean throttle body/maf, ecu reset(unplug battery then plug back in), try running a bottle of techron through your tank to clean the injectors...Lastly I highly doubt your spatk plugs need to be changed, but that could be another option.
