Autozone has Wells EGR valve listed for 98 Trooper, part number EGR1039. According to them the valve corresponds to O.E.M. #8-17096-178-0,
8-17096-178-2, while Alldata lists EOM part number as 8-17096-178-3.
The weird thing is that I cant find either 8-17096-178-2 or 8-17096-178-0 in Isuzu parts catalog... any1 know if that valve they're selling is good for Trooper?
