When i start my car up the idle is fine but after 2min i notice the idle going up and down slowly not jumpy? can that be idle surge and how can i fix it?

Check your throttle body and IAC might be dirty. Check for boost leaks. For first steps.

So should i remove the throttle body or i can just take my intercooler piping off and look inside of it to see if its dirty or not? I was thinking to take it out and use crc Throttle Body & Air-Intake Cleaner but it says do not use on vehicles equipped with a turbocharger.

Well just take the elbow off and look inside. Then move the throttle and see how black it is. If its bad than yeah look into that. Do a boost leak test first easiest thing. Some times the throttle body seals leak. Havent looked a throttle body lately but you should be able to take the iac out to clean it. I use seafoam deep creep. Amazing stuff for cleaning the throttle body. Just use a old toothbrush to clean.

You can spray soapy water on the TB to check for leaks. You can hear if the seals are leaking in the TB. The FIAV is another reason you could be getting surge. I blocked mine off and that is what fixed my surge. Your IPS can also cause surge too.
