Three O2 censer's, and one ABS censer.
Best car I have ever owed, hand's down. Easy to work on, cheap/easy to find part's. It's a 4 door Mustang basiclly. I highly suggest buying one if you wanna car for life.
The same sensors were the problem with my 96 p71. This is truly the best car I have ever had, and cheaper than all the cars I've owned. I'll never sell it.
