newpontiac Posted September 17, 2004 Report Share Posted September 17, 2004 I have a 1988 Oldmobile 98 with a 3800 engine bone stock. Can I remove the EGR and place a blocker plate over the original mounting without having my SES light come on? also will this hurt, improve, or not be noticable to performance? Does the EGR have any signal wires to the ECM? What wires are running to the EGR? Thanks, I am glad I have found this forum seems to be a great one.

94CutlassSLCoupe Posted September 17, 2004 Report Share Posted September 17, 2004 I'd say it can be removed because an '88 Engine should just have the vaccum operated EGR. But, i wouldn't do it because it leans your fuel mixture out and increases your gas mileage on the freeway. Atleast in cars with the electronic egr anyway.

newpontiac Posted September 17, 2004 Author Report Share Posted September 17, 2004 It has the electronic EGR it is a VIN C engine. will it still run lean without an EGR? Quote Link to comment Share on other sites More sharing options...
94CutlassSLCoupe Posted September 17, 2004 Report Share Posted September 17, 2004 if it is the electronic EGR, DON'T TOUCH IT..your computer will definately complain Quote Link to comment Share on other sites More sharing options...
99RegalGS Posted September 17, 2004 Report Share Posted September 17, 2004 The 1992 maybe 1991 also, Vin L 3800's didn't have an EGR. So you might be able to grab the Chip from one of those and put it in your car. Quote Link to comment Share on other sites More sharing options...
midnight rider Posted September 17, 2004 Report Share Posted September 17, 2004 Don't remove it!!!!! I used to have a 89 olds 98. It seriously fucks with the computer settings. Don't mess with anything on it other than maybe a custom intake tube and filter. If you so much as get a vacuum line loose, it will go fucking ape shit.

Do you mean an unstable idle when you unplug the vacuum line? You have to remember that 3800's are a MAF based system and it's more sensitive to vacuum leaks.

Brian P Posted September 17, 2004 Report Share Posted September 17, 2004 can I have back that plastic toy chainsaw I lent you? Quote Link to comment Share on other sites More sharing options...
midnight rider Posted September 18, 2004 Report Share Posted September 18, 2004 lol my son thinks you guys are funny for wanting to play with his toys. He will be 5 in december. Now back on subject, my car wouldn't run right with out the egr. I rplaced it and it run like it was supposed to. They are a very hard to tune engine in the olds lineup for some odd reason.... lol Quote Link to comment Share on other sites More sharing options...
