I have 06 corolla, codes PO606 & PO607. After reconnect of battery. Starts runs great ,scanner plugged in checking codes ,all functions normal then check engine lights up ,car stumbles and dies. Cranks over ,no start and total communication loss to scanner. Wait a while ,scanner gains communication and there again PO606 & 607. Disconnect battery and repeat. All else on vehicle is Oem and all functions great. 30yr experienced Tech. Traced all other routes. I believe this is a true ECM/PCM CPU OR PROGRAMMING ERROR. Thoughts on this one?????? Thx,Mike

Yes. There is a factory service bulletin for those codes (See "Tech Notes" above). The bulletin recommends reprogramming the ECM.
