Toyota Ed,
Hi, What will be the solution for code 24 and code 15?
Please reply thanks.

You know that you have a boost sensor I know you said MAF sensor, but some make and engine size has a boost sensor when this sensor goes you lack power as you described. so make sure this sensor vacuum hose is hooked up it also acts as a MAP sensor. give fuel when you accelerate

Go inside the rear hatch area remove the trim panel and manually trip the hatch release.

Hi

it sounds like the MAF sensor, or air mass sensor same thing. also check for leaks in any air pipes, look for rips or tears in the pipes common on a car this age.

Regards

-Sounds like dirty air flow sensor. Clean it to see if it will help or not before replace or check other area.

Good Luck

mass air flow meter

Go to your auto parts store & buy a can of "brake cleaner". Remove the MAF and spray it until the wires are shiny.
Do not use compressed air, that will break the wires.
BTW, the cat is covered for 8 years, under warranty.

Thanks. Let me know.

it might be your fuel injectors. The fuel injectors have been recalled. My 2000 gts was hesitating and i had the injectors cleaned and that fixed the problem. A month later i took it in for service and was advised that there was a recall on the fuel injectors.
