We could do with a bit more information, but in general you should be alright driving the car.
Depends what is happening. Is the check engine light (CEL) on all the time? Or have you just checked the ecu for codes?
If the CEL is on the car usually goes into a safe mode (limp home) and runs at reduced performance to get you home or to a garage.
The most important fault code to look out for is probably the air flow meter, you can do a search on here to find out the meanings of the codes. ;)
