Fun with the EGR tube

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

I literally just replaced my EGR tube as part of my never ending quest to eliminate all ECM codes, and my high idle. I decided to do it without removing the upper plenum. All I can say is wow! By doing this seemingly simple (at the time) repair, I discovered some more problems from my cars past. At some point a blocking plate was placed between the tube and the EGR plate, but the tube was left connected to the intake. I never noticed this �mm plate before until I took it off. And it was setting an EGR code. After nearly spending an hour trying to get one of the screws to go back into the plenum, I finally managed to attach the Fiero Store�s tube with success. The car now starts like a dream cold, with a nice low initial idle around 1200 as opposed to 1500 before. And it seems to have more power when going onto the highway. However, it did stall after about 3 minutes of running and had trouble finding an idle speed after I put in the new tube, but it runs fine now.
Even though the old tube was blocked off on one side, it was still causing problems. I inspected the tube after I took it off and it is not only plugged with carbon, but it has more holes in it than a piece of Swiss cheese. It would�ve definitely be causing air leaks in the intake. I suspect that the blocking plate was put in to simply make the problem �go away� and not have to fix the tube. I�m really happy about finally getting that new tube in but it took nearly two hours, several scraped knuckles, and endless profanity. I�ve had my car for nearly three years now and have learned so much with it. And that�s the end of my rant/vent.
