I need to know what the ignition timing is on this model. Have exhausted every other possible problem, sensors, ecm, exhaust, but the Clymers manual isn't helping. Please help. I have a timing light.

Is this a 2.5L or 2.8L engine?

Ooops, 2.5. Found the timing degree, but not running any better. Last thing to try is changing the ignition module, then on to the shop. Or get a new vehicle.
