Question about 2003 Ford Expedition
The service engine light is on and the coad reads the lean right and left bank.
What can I do to get this to go off and stay off? SUV is running very well and I pull a 7,000 trailer with no problems. This light has been on for about a month.
The dealer wants to charge me several hundtrd dollars to try and find what it is.
I am retired and do not have the income to just spend that kind of money when the unit is not causing any ptoblems.
Thank you for your help,
This is more than likely a vacuum leak, with the engine running listen under the hood for rushing air, another method to find a vacuum leak is to spray short bursts of carb cleaner in different areas (start by looking behind the throttle body, this is the most common place) and listen for a change in engine RPM, hope this helps
