How do you set the ignition timing on a 1993 Jeep Grand Cherokee?

Answer 1

The firing order of a 2.5 liter 4 cyl is 1342. The distributer only goes in one place, and the sensers control how much the timing is advanced. No matter what size engine the firing order should be on the intake manifold.

Answer 2

The 4.0L engine's timing is 100% under control of the engine computer and cannot be adjusted. Even rotating the distributor as was done on older engines will not change the timing, the computer will override if you attempt to change it by rotating the distributor. There is no need to worry about the timing, the computer actually does a vary good job of setting the timing where it needs to be.

Answer 3

The distributor is set to 0 degrees with a scan tool. It can not be done any other way.
