1996 Cadillac Deville V8 All Wheel Drive Automatic 130000 miles
on my dash board it goes across saying service emissions system I research it and it is saying the o2 sensors I was told I have 4 of them 2 underneath and 2 under hood is there anyway to find out what sensors is bad when I drive for a long period of time my car will just cut off in the middle of driving and it says on dash service emissions system. I am fixing to replace the 2 underneath to see if that is the problem my check engine light is on due to the emissions system. Or do I need to take it and get it diagnostic to find out what is wrong. Also I found out how to research codes on the dash hold the off button and warm button and 10 codes pop up and 8 of them say current and 2 say history the 2 that say history means what is wrong with the car. Please let me know what to do
have the same problem?
