    Before condemning the ECM, I would check and clean the ground connections for the ECM, and for the ground cables from the battery to the vehicle body or the engine to the firewall. If the battery is not grounded to both the engine and to the vehicle body, it can cause problems in the computer operation. But Toyotas are also known for defective computers.
