idle speed problems

[Frenchguy0]

Hey guys,i have a question for all the machanic champions out there.<BR>My car has a problem with the idel speed. It won't stay at the same level it goes up and down, from 1,500 rpm to 500 rpm without stalling and it happens wether the engine is in temperature or not. Would any of you know why and how to fix it ?<P>------------------<BR>Frenchguy0<BR>'92 GS Emerald Green<BR>crenia@hotmail.com

Is there a way i can check it out and have it fixed for cheap or would I have to change the whole air filter box ?<P>------------------<BR>Frenchguy0<BR>'92 GS Emerald Green<BR>crenia@hotmail.com

Not the box, the tubing between the intake manifold and the VAF/MAF. They have a history of cracking in the accordian-type ribbed section. You could use duct tape for temporary, but you'll probablly wanna replace that piece
