thankz for the help....i came across 4 different vac/emmision control info diagrams for 87 2.3,s and they all stated ignition timing to be set to 10 degrees btdc...thankz...also there is a wire that has to be disconnected when setting timing, it has a plug that pulls out and acts as a jumper when connected.....the label refers to it as the"in-line spout connector"
