Before replacing 02 sensors let me tell you a
story check engine light came on saying 02
sensors replaced with in 2 days light comes
back on saying 02 sensors at first thought
purchased bad 02 sensors took vehicle to
shop they said catalytic converter needs to be
replaced so what I did instead of using the 87
octane gas started using the higher octane
gas 93 and 94 long story short after 10 tank
fills and check engine light coming and going
off 4 times light is off and stays off if you are in
a hurry for light to go off you can try using a
converter cleaner like cataclean read some
good and bad reviews but mostly positive.
Now as far as the trac light coming on that
sounds like a brake system problem.
