Does the coolant sensor affect idle and hesitation???

Hello Board.

There are 3 temp sensors on my m103 engine.

1 controls the aux fan

1 shows the coolant temp

the other sensor I am unsure of (I think EZL, CIS-E).

The problem is that my car will randomly hesitate. I can drive for 30 minutes and then my car will randomly hesitate when I pull from a light. This lasts for a brief second, but it is very noticeable. It is very bad with my A/C on, I had to unplug my 02 sensor to tone down the ferocious hesitation. I read somewhere that that third sensor(I think EZL, CIS-E) can cause these symptoms. Is this true???
