I have a for expedition. This morning it was running fine i drove for about 5 minutes then had to pick someone up. It was in park and running the whole time. Then when i got in to drive I heard th abs system making that noise then i drive off and my car enging sounded like it wanted to give out. I drove it for 5 miles to work then worked for about an hour - and while i was driving back home the service engine soon light comes on what can this mean?
