My car's idle fluctuates when I am at a stop and I am begining to think its my IACV. I mean I wouldnt care that much except for the fact that the car goes down to about 150rpms and then fluctuates back up to 500-600rpms and then back down again. Im afraid its gonna stall on me soon.

Should I take it off and clean it or is it something else?

What do you guys think?

 

could be a number of things. check your vacuum hoses. might just be that. my friend had a problem simular to that, and he just needed to replace the o-rings on his injectors.
