I went to allparts and they said that theres like 4 different egr vaulves. He said i had to take mine off and tell him the part number. Then he said he thought he might know which one it is cuz its an auto. And he said its like $90. That sounds like a lot for an egr. Does anyone have an exact part number for me??? thanks!

 

Call your GM dealership, give em your VIN, it'll list which EGR you're supposed to be running.

 

GM PART # 17113381 for a 1993 automatic. $80 is dealer list, about $40 wholesale.
