Car stall while in drive and at a red light. Any idea of what cause is? on 2002 Mitsubishi Galant

In drive car stalls when at red light.

I would check for any check engine light codes first and foremost, I would also look for any cracks in the intake manifold that would cause vacuum leaks and therefore stalling. I have replaced several cracked intake manifolds on these cars.
Thank you so much! No engine lights on! My husband is puzzled so I am going to have him check this out now. Thank you so much! I appreciate your input and cannot thank you enough!
