AWeb80 Posted November 22, 2005 Report Share Posted November 22, 2005 Found the problem pic 1 Found the problem pic 2 Found the problem pic 3 This is how I fixed it 94 3100 I started my car this weekend and went on a family trip.....and it idled high.....like 1500-1800...... So, I went to pull the codes and I have no "B" slot....only an "A"....What the heck. well i figured i'd pull the battery cable for an hour or so and see if that fixes it.....(couldn't remember the idle re-learn) NO fixxy..... So I said what the heck and just drove it.... a 7 hr trip one way, and a 7 hr trip back and it ran great...except for crappy fuel milage (22mpg at 80mph)...and it still idles high... I got home and had time to tinker around....and found out that the EGR Tube that is in the intake right behind the throttle body is loose... I would move it and the idle would jump around...HIGH, Low, HIGH, Low.....so i found the problem ....how do i fix this.... I havn't had time to look at it since it isn't my daily driver i'll look at it this weekend.... Quote Link to comment Share on other sites More sharing options...
pwmin Posted November 22, 2005 Report Share Posted November 22, 2005 loose where...at the egr? i cant remember if theres a seal that helps hold it in place or not. take the 10mm nut and the 2 10mm bolts off and take it off maybe. make sure you have gaskets though. maybe im missing the point Quote Link to comment Share on other sites More sharing options...

I'll look at it on Turkey day....as I keep the car at my rents house and i'm 25 minutes away... Just wondering if anyone knew if there is supposed to be a rubber thing holding the tube in the plenum or something Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted November 22, 2005 Report Share Posted November 22, 2005 Im pretty sure there is a clip thats suppose to hold it on. Its one of those cheap ass clips that break everytime you try to take em off. Quote Link to comment Share on other sites More sharing options...

19Cutlass94 Posted November 22, 2005 Report Share Posted November 22, 2005 lol.... The only wire I could find that goes to the back of the TB is wrapped in electrical tape and is like a couple wires, not a tube? Quote Link to comment Share on other sites More sharing options...
pwmin Posted November 22, 2005 Report Share Posted November 22, 2005 i was thinking LQ1 also. :oops: cant remember how the 3100 is set up exactly Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted November 22, 2005 Report Share Posted November 22, 2005 I just went out and looked again, and besides from the "ports" that the EGR bolts onto that go to the intake, the only other thing attached to it are the couple wires that go to the TB Quote Link to comment Share on other sites More sharing options...
1990lumina Posted November 22, 2005 Report Share Posted November 22, 2005 Probably had no B slot because your car is OBD 1.5 is it not??? Anyway, sorry can't help you fix it though :(free bump Quote Link to comment Share on other sites More sharing options...

19Cutlass94 Posted November 23, 2005 Report Share Posted November 23, 2005 Allright, I see the little tube your talking about. Its like a really small tube right (Diameter wise) I believe that just snaps on. Theres no clips on mine or anything. Quote Link to comment Share on other sites More sharing options...

Theres no clips on mine or anything. hhrmm....mine is loose then....cause when i'd wiggle it, the idle would jump around cause more air would get in there..... and I could hear it hissing too.

cutty Posted November 23, 2005 Report Share Posted November 23, 2005 there should be a little rubber gasket thing on that hose, i had the same thing happen to mine. just one day that damn rubber gasket was gone, and caused my car to idle like that also. and if you need a pic let me know ill go take one and post it for you.

AWeb80 Posted November 23, 2005 Author Report Share Posted November 23, 2005 How did you fix it?.....where did you get the gasket? Quote Link to comment Share on other sites More sharing options...
cutty Posted November 24, 2005 Report Share Posted November 24, 2005 i fixed it with the spare PCV hose i had sitting at my house at the time, so i just swapped out the hoses. other than that i bet you could get the little rubber gasket at a parts store or something.
