i wouldnt think a o2 sensor would cause that much mayhem, but dont quote me. when did it start doing this, out of nowhere or what...

the timimg was at 18 degrees adv i set it back to 10 adv and it would not even idle for a few sec so i put it at 18 adv so it would run, i took to my shop(which is 3 blocks away) and had them thow it on the scanner got 4 codes 12,41,91,18. 91 is the o2 not switching, 41 is the ego i have no clue what the is, 12 is cant control rpm during high rpm check and 18 is no tach input

I cant really help you on this one, but it wouldnt hurt to at least clean the 02 sensors. Do it with a propane torch... it made my car run better, hopefully its just a simple fix like that, Good Luck!!
