FORD EXPEDITION SPARK PROBLEM

2005 Ford Expedition • 4WD Automatic • 82,000 miles

My 2005 Ford Expedition hestates when you accelerate. We replaced 4 spark plugs in 2010 and we just replaced the break boost yesteday. When we put the computer on the vehicle it said it was running lean. What suggestions do you have?

My first suggestion is, never change just 4 spark plugs. For your lean code, that is likely a back vacuum leak somewhere.
