June 11, 200718 yr Please forgive me in advance, but I can't find anything here on tis very stupid question. I suspect that my egr valve is not seating all the way. Would this cause enough of a change in vacuum pressure that I might notice a significant drop in power and advance? Is there any way of cleaning it? This may be multiple causes, but any advice on the subject would be greatly appeciated. Thanks Guys, Nate

Thanks Guys, Nate If the EGR is stuck open/not seating then yes it could make the drivebility of the car suffer.
June 11, 200718 yr I am not sure it would nessecarily cause a vacuum drop though. Check all the other things like vac hoses and throttle body base seal.
June 11, 200718 yr Author ok I've checked all the hoses I think. The advance is still not coming on. any other ideas. do you think if the egr was stuck open it would inhibit the advance?

Your car wouldn`t idle if the egr was stuck open. The vacuum advance diaphrams commonly rupture. Mechanical advances get gummed up and stuck too.
