Subyaddict Posted June 11, 2007 Share Posted June 11, 2007 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 Quote Link to comment Share on other sites More sharing options...

Thanks Guys, Nate If the EGR is stuck open/not seating then yes it could make the drivebility of the car suffer. Quote Link to comment Share on other sites More sharing options...

Gloyale Posted June 11, 2007 Share Posted June 11, 2007 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. Quote Link to comment Share on other sites More sharing options...
Subyaddict Posted June 11, 2007 Author Share Posted June 11, 2007 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? Quote Link to comment Share on other sites More sharing options...

The vacuum advance diaphrams commonly rupture. Mechanical advances get gummed up and stuck too. Quote Link to comment Share on other sites More sharing options...
