Need some help

[sina27]

Hey Kick. 
Thanks for all the help. 

UPDATE:

• I changed out the ECT sensor, thermostat.
  
• Car is still lacking a CAT, and there is still a large hole in exhaust pipe right before muffler (will be fixed soon)
  
• The tracker still idles weird - 2000-3000 rpm when starting it cold, and sometimes it "surges", like it shoots to 3000 then back down to 2500 quickly and repetitively. 
  
• The idle stays high for at least 7 minutes until it starts going down 
  
• Once warmed up, it idles at ~500 rpm. 
  
• No smoke during idle. I see smoke when giving it gas. 
  

You mentioned that I should diagnose the FPR next. Before I do this, I was wondering if you can look at my ISC hose routing and confirm it is routed correctly. The ISC looks new on my car, so I assume the previous owner recently changed it, and I want to make sure it got installed correctly. 

Looking and you ISC photo, your image shows the bottom two plugs are coolant, and the top plug to "air". 
I took photos of my routing, and I labeled them. Can you confirm the routing is correct? 

Here are my images of the ISC:

• First photo shows the top ISC nipple connecting to the intake air, shown in red (#1)
  
• Second and third photo shows the bottom two ISC nipples (in green and blue)
  
• Third photo is supplement
  

So in your photo you show that the bottom two hoses attached to ISC are coolant? The routing I have in my photos shows that one of these hoses goes into the base of the intake manifold (green # 2), and the other hose goes onto the top of the intake  / throttle body (shown blue #3). 
Is this correct? If the bottom two hoses are coolant, why is one of them being routed back on top of the intake? (see last photo). 

If the ISC routing seems correct, do you think my issue could be related to the DASHPOT?? I can look into the FPR or DASHPOT and possibly replace them. 

Thank you so much. This has been a headache and hopefully I can solve all this soon.
