Problem With Idle

I just bought a 1998 trans am WS6 A4, and whenever it idles. it fluctuates about 50-100 rpms constantly. What is wrong with it? Thanks

Does it have some kind of after market cam? 50-100rpm fluctuation is that big a deal.

the only mods it has in 3.73's and flowmaster exhaust. The reason i am concerned is that it is pretty noticable. You can hear the engine reving up and dropping by itself constantly every time i idle.

Is it normal for the idle to constantly jump around, or is it supposed to just sit there?

the normal idle should be @ 0.6 rpm (as computer set)

check the fuel filter (replace it)

or injectors need for clean! ..it seems the computer is trying to get idle operation .....
