'89 Buick Century. Getting MAF sensor error (code 34 (and no, not the MAP 34, this car has no MAP). Runs extremely rich....can't get it to stay running. But I sure as hell CANNOT find the EGR. I have looked all around the intake....it'* almost as if this car doesn't have one.
Is it possible that this car doesn't have an EGR valve? I have looked EVERYWHERE for this friggin valve and simply cannot find it. Only vacuum lines I trace go to other things, but no EGR valve found. I am staying with a blocked Cat on this car as the problem.
I know some 92 Bonnevilles didn't have the EGR. It'* possible that you don't, that'* about the time they were tossing various emissions things on and off trying to make the government happy and having a horrible time with the cars.
