How do I advance the timing on an '87 3.8? February 28, 2010, 10:21:19 PM My current timing is at 0 degrees and needs to be at 10 for CA emissions. How do I advance it? Do I do it mechanically or with the vacuum advance? Whats the difference? Quote Selected

How do I advance the timing on an '87 3.8? Reply #2 – February 28, 2010, 11:42:01 PM I know youd use a timing light to advance it mechanically, but Im asking if there is a special procedure for doing it on the V6 Cougar. Do I just rotate the distributor cap and call it a day or is there something more involved? Quote Selected
How do I advance the timing on an '87 3.8? Reply #3 – March 01, 2010, 12:11:04 AM There is no vacuum advance. Spark advance is controlled by the ECU.Unplug the SPOUT (Spark Out) jumper and set the timing by rotating the distributor.(not just the cap.)The SPOUT jumper is in the yellow wire to the TFI module.

How do I advance the timing on an '87 3.8? Reply #14 – March 03, 2010, 10:08:17 PM You want to adjust the "base" timing, with the spout disconnected. When the spout is connected, the EEC has control of the timing. If you adjust it with the spout connected, it will be way off. Quote Selected
