Question about Lincoln LS
The engine in my Lincoln surged to high revs while I was parking last night. What would cause this problem, and how is it repaired?
Could be related to brake power booster, requieres a litle bit of troubleshoting, try to listen for an air/vacum leak.

Check for vacum leaks on hose going from the intake to the brake booster. Also check the dodge.com website. Click on the for users button. Enter in last eight digits of vin and see if pcm (computer) needs a update, or if there is any other open recalls on the van.

1.Verify that the cooling system is full of coolant and there is no air in it. 2. Remove the air boot from the throttle body and cover the throttle body with something that will stop the airflow . the Fast Idle Valve is the problem.

Check for a vacuum leak in the vacuum assist diaphragm. A leak can allow far too much air into the intake manifold, causing an increase in engine speed.

The missing while accelerating is likely due to ignition coils and/or spark plugs going bad. The missing while in park is a normal thing. The car has a rev limiter that will not allow the engine to rev to higher than 3000 RPM while in park.
