Check for vacuum leaks.

I have seen a bad MAP sensor cause stalling issues when coming to a stop a few times. Try unplugging it and go for a test drive.

spraying carb cleaner around the engine vac lines will help find a vac leak, if the idle jumps, you found the leak area.

I already told you this guy, check for Vac leaks around the ends of all Vacuum lines while the car is on.

If RPM's spike, you have yourself a vac leak.

As you mentioned, you put in new vacuum lines already, you could of routed one wrong also.
