wow, are you serious? no other problems/fixes on car? currently i'm having a cheap Champion fuel filter from autozone. getting around 23MPG. not sure if i want to replace the fuel filter with toyota one as of now, but it might be worth it though... in past i was getting up to 28-30 MPG.
also i'm using now NGK Laser Platinum plugs - they cost a bomb (around $9 a piece on amazon), but they make my engine run real smooth and idle much better than with former Bosch Platinum+2 plugs.
