Hey guys, I just wanna run this by you before I go out and buy block off plates. My car idles real bad when it gets hot(interstate driving for about 30 minutes) rpms below 500 and my vac gauge is reading about 10 as opposed to the 20 it reads when idleing well. If I disconnect the vacum line that comes from the throttle body to the erg my car will idle perfectly fine but when I get off the interstate sounds like i got one hell of a vacum leak going on. I don't wanna just throw money at it and hope it solves something so I just wanna know what you guys think.
