All, I need some help with my 1997 GTS. My IAC is starting to fail. I have tried cleaning it as described in may different posts and it does not seem to really help. The number on the side of my IAC is 5245352. I have tried to purchase a replacement 5245352 several times now and they are all too short from the flange to the tip of the plunger. I read on forums that 53030657 and 4778637 can be used as a replacement. I ordered one of each to try but it is also too short. See the attached picture. The one on the right side is my stock one. Does any one know what part number I should order to get the longer version I need? Thanks.
