Ok, I dont even know what this could be.
My car starts fine, everytime. it drives fine, revs all the way toredline all the time.
it will idle fine.

So.....When I slow down ( no matter what gear) the RPMs drop ( naturally..) But sometimes when I slow down, my rpms drop all the way to zero, and the car dies. Then I turn the key all the way off, and then back on, and then it will start fine. But it dies almost everytime I start to slow down. but it will idle fine if I rev it to 1000rpm at idle, it will fall to 900 ( good) there is no studder, no misfire, no idle surge.

So what could this be????
 
Sounds like a vacume issue. I had a similar problem before and i traced it back to a leaky vaume line killin my idle on decel.
