2002 V6 XLE Camry - Engine Light On, VSC Light On, TRAC OFF light on.

The engine light just turned on, and within 10 miles the VSC and TRAC OFF light also turned on. When I took a turn the Engine light blinked a couple of times. In normal driving condition I feel "bucking". Looking at the instanteneous fuel consumption, it seems that I am getting 14 mpg instead of normal 20-22 mpg when driving at constant speed of 45-50 mph on highway.

Any idea what caused it ? Still did not have a chance to look into the codes yet. Planning to take it to auto zone to check the codes.

Any pointer will help.

Thanks. Sid
