I am looking for someone competent that can adjust the timing on my 12 valve in the Spokane, Wa - Coeur d'Alene, ID area. If anyone has a positive experience with having this work performed on their rig, please let me know. With the information I have absorbed reading in this forum, the answers I get from businesses regarding how they perform the work makes me suspicious that they may not know how to do the task properly. I only want to do this once, as I have learned it is not a cheap procedure (225. 00 - 250. 00) . Any input appreciated!
