Here is the code I just got..

"P1178 Maximum Positive AMFR Correction Fault"

Right before I picked this Disco up, the previous owner had it in at the local LR dealer to fix a bad ground for fault: "P1185 Oxygen Sensor Heater Circuit Open Upstream"

So I am wondering if there is still a bad ground somewhere... grr... gonna take the MAF tomorrow morning, clean it with some contact cleaner and reset the sensor..
