I recently purchased a used 2002 Ford Expedition with 103,000 miles and took the family on a trip. The first thing I noticed was at around 1500 rpm and 2000 rpm, while gear changing, their is a vibration that tapers off after a few seconds. I have tried giving it more gas to see if it does this under pressure and it doesnt. Only when driving under normal circumstances. It doesnt vibrate when I am sitting idle and revving the engine nor does it miss. I have tried to see if anything would come up on an error code reader but nothing shows up. Any help would be appreciated. Thanks
