Ok, I read the codes on my 94 Bird. I got 4 codes(P1130,P1131,P1132,P1406). The first 4 were indicating that the O2's are bad which make sense because it'll blow black smoke and load up after cruising for a while and ping some under WOT. The fourth code is giving me trouble though. P1406 in the book is "Differential Pressure Feedback Sensor Downstream Hose Off or Plugged". What does this mean?:shrug: Why would the diff. have a sensor? It's an open diff with ABS. Can anyone help me?
TIA
