88 se idle problems
 

Alright so im picking up my first rx7 this weekend, trading it for my old civic and some cash. Im in love with it already and only drove it once. did a little research on the rotary engine and everything.. and im happy with them, Im ready for the crazy rx7 world lol.. or at least i feel like it..

but i dont know that much yet so bare with me...

So when i start the car i have to tap the starter it sounds like.. like turn the key 2 or 3 times.. and idk if thats just because its been sitting and it needs a good run down or not? also when idling its really irratic and it starts off high, then when i go to slow down to turn or park it it stalls out???? didnt know what the problems would be.. i was reading somthing and alot of people say its the Bac valve, or could be a compresion problem.. to me engine sounds good and it runs good so im not thinking its compression? So wanted some help?
it would be nice!!

lol thanks peeps!
