Check engine light flashing!!!

Hi there everyone..im new to the mustang scene, i just picked up a 96 3.8 about 2 months ago and the check engine light was on, i got it checked and they said it was misfiring and a bad o2 sensor. But just yesterday the check engine light started flashing? Has anyone ever encounted this problem?

Re: Check engine light flashing!!!

Flashing represents a misfire is happening at that moment,,also the reason it warns you is that its doing damage to the cataylitic convertor,,A small misfire is ok,,but if its flashing you need to find the problem,,because it doesnt take long to cook the cataylitic convertor,,but DONT change the o2 yet,,misfire codes also send o2 codes too,,fix the misfire,,and clear the codes,,and if the o2 sensor code comes back then replace it
