on thursday my monitoring exhaust gas warning light was on, but it was off on friday. Iv been driving it 4 2days with no problems but the light came bck on again last nyt. Is it okay to drive?

If it's running ok I wouldn't worry too much but it will have logged a memorised fault which may be worth getting checked out as whatever it is may end up causing you problems at some point in future...

Most proberbly an H02 sensor or wiring fault but it needs fixing really as if it is a faulty H02 your fuel consumption will start to increase.
