The ECM does. The module is only a pickup and a signal conditioner.

There is a tan wire with a black stripe that disables timing advance when disconnected, so maybe that's whats going on. Its near the realay center on the firewall.

Where is a ignition module in a 1988 Acura Legend?

The PGM-FI unit is located under carpet at the passenger side. It covered by frame. Good luck. The ignition control module of any late model Honda/Acura product is always the PGMFI computer, which controls all fuel delivery and ignition timing coordination. Now, if you have a problem, that is ignition related, first replace the plugs, then the wires, and shortly after the ign coil itself. That's how you approach a Honda ign prob.

There is a problem in the distributor. Either the pickup coil or the ignition module are defective. It may be cheaper to purchase a remanufactured distributor.

What causes a 1994 Honda Accord to start first thing but after driving a while the car turn off and start back on?

Most likely- bad ignition module inside the distributor. Easier to change the whole distributor and reset the ign. timing, but costlier than digging out the ignition module to replace it. May also be the ignition coil, a very common problem, but will usually show burnt contact when you remove the dist. cap. Note: a new coil usually comes with a rebuilt distributor. You may need a casting number off of the old distributor for the parts guy.

What is the timing advance on a 1993 Chevy Lumina?

Where are the timing marks on a 1996 Chevy Corsica 2.2 engine?

There are none. Ignition timing is not adjustable. Ignition timing and spark advance are handled by the engine controller module and the ignition control module, with inputs from various sensors. The engine controller is located by the passenger kick panel. The ignition controller is the thing the ciol pack mount on...it runs about $110 new. The ignition controller is often the cause of rough running, or idle problems as the spark advance function tends to crap out on this model of DIS ignition. Producing a constant error code, and therefore a constant check engine light.
