I replaced the timing belt on my 2003 is 300. now the engine light is on and the trac light is blinking. I made sure all the timing marks were on and plugged in all sensors. The car runs o.k and starts fine. what could be the problem
I had the same problem with mine, mechanic said it was a result of the O2 sensor (s) needing replaced. He replaced them and problem was solved.
Check all sensors are pluged in then restart your system by unpluging the battery for a few second and pluging it back in and start your car and test if still on get it checked
