How do you get the diagram to tell you how to have the correct marks for the ignition timing for a 1993 Plymouth sundance?

Answer 1

By diagram, if you are refering to the Emissions Control label located on the under side of the hood, it is only good for telling you what your timing (x degrees before top dead center (BTDC)) should be, given the engine you have. Haynes sells a service manual (about $17.00) that does a pretty good job of explaining how to go about setting the ignition timing on your engine, including descriptions of where the timing marks are for your engine and how to perform the timing adjustments.
