I hate to interject, but the "ea/cc/isc" unit and the wiring harness issue.

Is the ea/cc/isc unit another name for the throttle actuator?

Does the actuator go bad or just the wiring harness?

Can the wiring harness be replaced, or do you replace the whole throttle actuator?

It's just about $1,000 to replace the throttle actuator.
