Find and repair your vacuum leak! That's it. Maybe use a straw on a can of WD-40 to pinpoint it more. Just dont spray it on an ignition source!

i did and guess wht rite behind where the power steering pump is had a vacuum leak. its hard to explain but the flap inside the black top intake, on the side has a small round cover tht pop off i guess, temp fix i used silicone and it runs perfect! so to others tht have this similar problem, check tht out first. thks for the reply. but dont use silicone cuz it will suck it in the head and cause more problems, simple repair. replace it.
