After installing a replacement distributor. I read I need to check my timing. Not
quite sure the correct or proper procedure. Some says disconnect the idle
sensor and some says need not to. Where is the idle sensor located? Where is
the idle adjustment screw located? Label the hood: 700rpm @ 20 degrees.
Crankshaft pulley location is something else.
Which engine? 4 Cylinder? I did not think that the distributor moved very much, if you did not removed the head or move the timing marks it should be very close, When you removed the older unit did you make the marks to show its location if not you should have made a mark from engine onto distributor and then moved it both directions to see how far it moves and mark each way where it goes to, making line mark from first mark on distributor continue onto engine head then install the new one and move it to one side or the other all the way put mark on new one from the mark you made earlier and then move distributor to the center lining up marks and can check by moving distributor to the other mark it should line up then move it back to the center mark.
After making marks yourself the distributor will have one mark on it and the head 3 marks if you make your marks, may check to see if it already has marks on it.
Otherwise use a timing light and locate timing marks down by crank and move the distributor until they line up.
