It is time for a new ECU but you are well out of warranty so it will cost you a lot of money. See this thread: 06 corolla - bad batch of ECM's?

TSB for this common problem : http://ww2.justanswer.com/uploads/sn...lla_tsib_5.pdf

That is the US version TSB, I am sure there is a Canadian equivalent but it doesn't matter too much as it is out of warranty.
