Cooling system pressure

[enkeisroller]

Alright Im working on trying to keep my engin from reving when it is cold. It revs like vrom vuh vrom vuh. Only at idel until it warms up. Alright some have said to bleed my cooling system. Well today i did that but when I undid my radiator cap from it being hot nothing came out, and it didn't sound like any air was realesed either. I dont think this is right, is it? I thought when you undo a hot cap fluid and air should come out. What should i do? Get a new cap???

Alright well i said hell wtih it and blead the system anyways. But i dont knwo if it is goingto help????

I have already blead the system, I do know how to do that, really just curious about what you guys think about my cap and the reving

Depends how much pressure there's still left in the cooling system. To be safe, just get a new cap.
Did you check/clean the fast idle valve on the tb for your revving problem?

i ve seen a lot of cars having problems because of the radiator cap or teh neck of the radiator is cracked !
