Help with engine Stalling
Well my FD is not a daily driver so it doesn’t get driven very much only like on weekends and also gets started during the weekdays and has a Mazda reman that hasn’t been broken into yet. Well my problem is when driving the car it runs good but after driving it for some time when getting close to a stop light and putting it in neutral to come to a full stop the RPMs drop very low some time almost killing the car and when light turns green and put it in 1st and start to rev the car to get going sometimes the RPM just drop very quickly and kill the car. Can any body help me out on with this problem thanks?

idle might be too low for a new engine that hasnt built compression what's your hg vac at idle? maybe turn up the idle some under the elbow i had the same issue and my car has 30k miles on reman..it was idling at 400-500rpms when thrown into neutral i adjusted the tps and the actual hard idle control now its much better..check ur grounds too my car would stall once in a while when the clutch disengaged very quickly into turns...i got under the car and the main ground connection was loose and i tightened it things are a little better now

No the car is running fine no bogging well I cant really tell yet since I cant push it yet because its still breaking in and when the headlights get turned on it only goes up in idle witch sounds normal to me when you and any other load on the engine.

If your clutch switch is indeed going south, the idle adjustments won't help.
