My 91 Nissan Sentra will not idle while driving when outside air temp is above 40 degrees. When engine vaccum increases while coming to a stop, it dies. What is the most likely problem? Thanks in advance! Lyle

Try checking the idle air control valve or aux air control valve.

That happened to me. It was a bad air flow sensor. Don't know if yours
is the same, but worth looking into.
