Customer welcome to JustAnswer!.

If your Ram Van is in the years of 1988 to 1991, ignition timing is set at 10 degrees before top dead center.

To put the engine in default for setting base timing, you will need to disconnect the engine coolant temperature (ECT) sensor, which is located on the intake manifold near the left front area. It's a 2-wire sensor, pointing straight up. Disconnect it while the engine is running and when the CHECK ENGINE lamp comes on, you're good to go for setting timing.

You can choose to erase the code when you're done by doing a battery or PCM disconnect afterward. Either way, the light won't be on after the ECT has been reconnected and the key has been cycled.

Ignition timing on 318 engines from 1992 forward have no means of timing adjustment, but spark timing can be retarded in 2, 4 or 6-degree increments by using a factory scan tool, should you have problems with engine ping.

Let me know if there's anything else I can help with.
