      Do yourself a favor and just go read the code 32 troubleshooting flowchart in the factory service manual. You'll learn something about...

      I purchased a new EGR valve and got it installed. It was Advance Auto Parts part number EGC1114. The actual part did have a N stamped on...

      Did he not already state that he could draw air though the EGR valve? Which would then mean that the valve does not hold vacuum. A...

      Yep. but if it is stuck it wont hold vacuum. I think it is worth the effort to attempt to free it up and then try to pull vacuum and...

      EGR valve is shot based on your testing--inability to hold vacuum. Being a TBI, you almost certainly have a negative-backpressure EGR...

      It's quite common for the diaphragm to fail. Just make sure you get the correct replacement as there are 2 different types for these...

      Seems unlikely. That second "nipple" has no hose barbs. IT'S A VENT. It's SUPPOSED to be open to atmosphere--although ideally there'd...

      On my '89 Firebird with it's 305, the EGR passages in the intake manifold were plugged solid. I never saw that code again once I...
