MONEE_SHOT

Ok guys im still very new to rotary and obviously am looking for some help here. Heres a little backround. I have a 91 n/a rx7. It has 111,000 miles on it and I dont think its ever been re built. I have only had this car for maybe 3-4 months now. This is what its doing....when i start it up in the morning or anytime that the engine is cold and hasnt been running in awhile it runs perfect. It pulls pretty hard (probably as hard as a n/a 13b can pull) and drives very smooth. After about 10 minutes or so it starts to miss and the acceleration drops off pretty bad. It never wants to quit but has a very noticeable miss. Another issue im having is if i drive the car for awhile....shut it off for more than say 5-10 minutes....it WILL NOT start back up right away. it takes like 8 tries to get it to want to fire again. There is no smoking or oil leaking. any ideas????

I'm not too sure about your first issue, but for your 2nd issue, it sounds like you have leaking injectors, a common issue on our 7s.

check out the Water thermo sensor on the back of the waterpump(behind the alternator) to see if A:it is hooked up, or B; it is In Spec.
It sounds like that Sensor is Good Cold,But it can't send a signal when the car warms up,so your Car is Running Real RICH,and flooding the **** out of it.(it sends signal to the Ecu and varies fuel from cold to hot).
also Check to see if your Catalytic converter is OK..If it is stock,it is most likely Shot,and could be Plugging up.(if the cat is Deleted,then Disregard).
