idle problems after removing a/c system.

[fastpace]

I have this recent problem with my car (240sx). Whenever the car is warmed up it idles at 830 rpm. And then at times the idle dips between 600-800 rpm for about 5 times and then goes back to 830 rpm and then continues this process. I don't really know how to solve the problem. Was wondering if anyone can throw some ideals out to me to help me out.

hunting like that can be a symptom of a vaccum leak, also check the maf connection and make sure it has a good ground, as well as making sure the air conditioning idle bumper (sorry ill look up the right name if you need it, i think its somthing like ACC or somthing...) is blocked off completely

my freind if there was ever a case for the wiggle test...

wiggle everything under the hood and then hose everything down with carb cleaner(engine running). if you see the motor pick up you found a vac leak.
