1-3-2-4 Posted September 13, 2011 Share Posted September 13, 2011 I have reason to beleave my oxygen sensor is going because of hesitation once the car warms up.. But here is the thing... the other day when checking my belts and my AC charge I decided to start the car and rev it I noticed the EGR did not move.. Does it only move when the car is warmed? I did remove my engine to do the headgaskets and all and i'm about 90% sure I checked all the vac hoses and I have no codes regarding the EGR.. just curious here on why I never saw it open up when blipping the throttle. car is a 97 outback.

1-3-2-4 Posted September 13, 2011 Author Share Posted September 13, 2011 I'm not sure if you are trying to be funny or being serious but yes when the engine is warmed up and you blip the throttle open quickly you should see the EGR diaphragm slide open and close back when the rev drops.. works on vacuum. Most tend to get stuck open which causes a huge vac leak which makes the car hard to start or stall when at idle. I'd have to check tomorrow after I get home from work when the car is up to temp.

jamesm113 Posted September 13, 2011 Share Posted September 13, 2011 if your egr is stuck you'll get a CEL Link to comment Share on other sites More sharing options...
I Donated broknindarkagain Posted September 13, 2011 I Donated Share Posted September 13, 2011 I was being serious. I've never bothered to look at an EGR to pay attention to that lol. -broknindarkagain My Current Project - Click Here COME AND TAKE IT "The only thing necessary for the triumph of evil is for good men to do nothing."

400obw Posted September 14, 2011 Share Posted September 14, 2011 The EGR probably won't open just by "blipping the throttle" you can slowly rev your warm engine and you should be able to see it move tho. You can also use your finger to open it and see if it's stuck or you have blockage. If you open the EGR with your finger the engine should stumble if it doesn't you have blockage Link to comment Share on other sites More sharing options...

The EGR helps can help save your valves by keeping combustion temps down for one thing... Link to comment Share on other sites More sharing options...

Having an EGR does keep your combustion temp down, however not having it wouldn't burn up your valves. EGR is there to reduce nox emissions -broknindarkagain My Current Project - Click Here COME AND TAKE IT "The only thing necessary for the triumph of evil is for good men to do nothing."

400obw Posted September 14, 2011 Share Posted September 14, 2011 hmmm nice to know LOl. Sorry for the stupid ? then[/quote Hey no stupid questions, some cars are more prone to burnt valves and keeping the EGR valve functioning can mean the difference between doing a valve job or not. It is also for pollution control, reduces NOX emissions if remember correctly. LOL Link to comment Share on other sites More sharing options...

urdrwho Posted September 14, 2011 Share Posted September 14, 2011 From what I have read it should move about 1/8 inch when you blip the throttle. The EGR probably won't open just by "blipping the throttle" you can slowly rev your warm engine and you should be able to see it move tho. You can also use your finger to open it and see if it's stuck or you have blockage.

1-3-2-4 Posted September 14, 2011 Author Share Posted September 14, 2011 I was in a bit of a rush today so I never got the video of it moving but yeah about 1/8 to 1/2 it movies. Link to comment Share on other sites More sharing options...

ladysmanfelpz Posted September 25, 2011 Share Posted September 25, 2011 ive had egr problems forever and can't get it my cel to go away. So should i try this and if my egr doesn't move get a new egr? ive cleaned all hoses to it except for one pipe to check out below the egr just cuz i didn't have a tool to reach the bottom bolt Link to comment Share on other sites More sharing options...
1-3-2-4 Posted September 30, 2011 Author Share Posted September 30, 2011 Sorry took so long to get back but it could be stuck because of a few things.. carbon build up.. You can try to lightly push it open slightly to see if it will unstick it. If it's really bad like on my forester I used to have, I had the EGR stuck open and it was a pain to start.
