i bought a runner a few months ago. i wish i could could figure out the bad gas milege. im getting maybe 10mpg. i changed mass air flow sensor. new air filter. alternator and distributer. i just dont understand


and i now im having a problem with the battery... it will stay a good charge for a few days.. then it will die. i will take a battery charger at night when it dies and it still wont stay a good charge.
