Thank you for using Just Answer. How many miles do you have on your corolla? Does it have any driveability problems, or does it continue to operate as it always has? How many miles do you have on your car?

about 56,000 miles runs great, transmissiom smooth, didn't want to run after a fill up with gas would not idle you would have to raise the engine rpm;s with your foot for about 30 seconds then everything was ok, replaced gas cap it seemed to help the idle but i get the codes po171 if i check it when the check engine first comes on, but if i drive a few more miles then check it i get 3 codes po171,po441, po445 thanks car has good power everything seems to operate good
I have good news for you!!!!! Your corolla is exhibiting symptoms consistent with a service bulletin from Toyota. The repair involves replacement of the ECU (engine computer) and is covered under the federal emissions warranty. This warranty is in effect for a period of 8 years/80,000 miles. The service bulletin is TSB EG041-07. You should be able to take your corolla to your local Toyota dealer and have this repair performed absolutely FREE!!!!
