Car stalls at lights. Check engine light on. Running lean on Banks 1 & 2. MAF? on 1996 Ford Thunderbird

When car stalls, it starts up again no problem. I also notice volt gage drops during the rough idle before stalling. Told it could be a vacuum leak somewhere along the line. This problem does not happen but occasionally.

yes vac leaks will cause this and so will mass air flow. have a smoke test done b4 repl maf could also be fuel pressure,inj issues or plugged fuel filter

Thanks for the response! Btw, I had the intake manifold replaced since there was an issue with these.
