Question type: General

1 Answer

The ECU controls the rich and lean. The EU gets it's info from the water temp and block temp sending units (same part, 2 different spots). Replace ECU. Also, make sure your Air Control Unit is working. That gizmo has a hose going to the front and rear of it and has it's own small internal heater the size of half a small postage stamp. Within it is a hole that a shutter opens and closes. Open when cold, closed when warm. Shutter works via the little heater and thus bending metal. Sits on top drivers side of engine.
