searched-jumping idle
ive searched and no one seems to have this problem.the car is warm and i just let it sit in neutral,then it goes crazy,the idle jums up and down,and it sounds like hot rod when it does that.its kinda strange.the idle goes up about 1500 then drops to 7 or 800 then jumps back up and keeps jumping. i was thinking it would be my tps but not sure.the car is GTUs N/A NO MODS.any help or advice is welcomed and thanks in advanced.

Your problem is probably two things...
Thing one: Make sure the TPS is set to 1volt, engine fully warm, then
Thing two: Set the idle speed to 700-800, again engine fully warm...ground the initial set connector, crank the engine and adjust idle to proper speed. Don't forget to remove the initial set connector ground
Once you've gotten the idle speed adjusted, go back and verify the TPS setting.
If this doesn't solve the problem, set about finding the vacuum leak.
