engine light on. 2001 1.3 sirion

Forum: 

It came on today, car still runs and noticed difference in the way it runs. any ideas.

Only way to know what's

Only way to know what's happened is to plug in a diagnostic tool into the ODB-II port. That way a code will be displayed. If the car is not running right, it can be anything from a sensor to coil packs.

Engine light

Happened on my YRV...took it to a dealer, who for next to nothing found nothing wrong, reset the light. That was 30k miles ago. No recurrance! Software glitch the man guessed.

reading the ecu

Just had it looked at, came back with miss fire on 1,3 and 4. Car was running normal so had it reset. If it comes on again then I'll look at getting a Ignition pack.
