Ok i pulled the throttle body and cleanded the 2 ports in there and sprayed some cleaner down in the egr.I've read in another post that the sylenoid has two prorts something about boost and i cant remember the other now when the car idles there is no vac on the egr i saw that it has to be at temp and at rpms 4000 gs and up for vac to come one could the sensor or sylenoid be bad and what are some ways to check.Thanks a bunch!
