2001 MPV stalling
 

2001 MPV with 125k miles. It is stalling when stops at traffic light. It is fine as long as it's moving. When I step on brake RPM dips below 1000 and stalls.Could it be MAF? I got a code P740 (740 The engine's running faster than it should for these speeds, so I think thetorque convertor clutch lock-up system is bad )
What are the symptoms for bad MAF or intake temp. sensor?
Thanks
