Egr low flow guys....I tried testing the EGR valve by applying vacuum at idle to that port on top of the valve to see if the engine stumbles. It wouldnt even hold vacuum so I'm guessing I need to shell out $140 for a new one. Before I do that I want to see if anyone else has had this code before.....I know it could be the Modulator or VSV underneath the intake. If any of you can go out and test that port on top of your egr to see if it holds vacuum that would be appreciated so I can stop second guessing myself.
