b16 Fluctuating idle...could it be my TPS or Vacuum leak?
 

I have a b16a2 in a 95 Civic EX

When i start the car revs up and down constantly! I tried cleaning the the Throttle body and the IAC Valves. but no luck.

Also I found a hose that wasnt connected to anything. Could someone tel me where is goes or show me!

welcome to the forum. normally it is the ICV. wondering if you might have replace your rad fluid and have air in the system to bleed out.

the line you have marked goes to the manifold absolute pressure ( map ) sensor top area of the engine.
