Hi! My 2001 nissan altima is vibrating when stopped on traffic in drive, I have to put it in neutral when in traffic, this way it does not vibrate and today the service engine soon came out, please if someone knows anything about it let me know. Thanks

Begin by:

. Checking for codes, by attaching a code reader to the data link connector under the dash.

. Changing the automatic transmission fluid and filter, if it has not been done in 30,000 miles or two years.
