Jerking feel at about 65mph
2004 Nissan Altima is smoking through the
exhaust at start up for 2-3 min. The car drives fine
until you get to about 65 mph then it will start
jerking (best way i know how to explain it) the first
time it jerked the service engine light blinked on
and off but stayed off. Does anyone know what
this could be? Can I take to Auto zone to check for
codes without the service engine light on? Please
any information would be helpful.
