It is going into closed loop at that temp. This is when O2 startes adj. Fuel ratio a slow to respond O2 can cause hesitation. If you can find someone with a old OBDI scaner you can read component info. If O2 is got alot of miles on it a good place to start. Let me know and I'll try and get it running smooth.
