1998 Ford Aerostar trouble codes

Hi:

Code P1537 - Intake Manifold Runner Control Stuck Open

Code P1538 - Runner control stick

Code P0171 - System too lean bank 1

The runner control can cause the lean situation. The part is a big job to replace, but I have an idea. It is probly just the clip that conects to the actuater bar. Remove the Intake plentum first just to see. It's just a little clip no bigger than an eraser on a pencile. Anyway, it's not a real hard job, just time consuming. If you can use a torque wrench. It will take about 4 hours to complete.

Let me know what you find.
