Here is what I have. 1997 Disco, 100k miles. Bought recently. Check engine light on. Got the codes from the OBDII AutoScanner. Here are the codes that it threw and what it gave on each code. 1. P-0326 knock sensor, 1ckt range/perf, bank 1 2. P-1193 manuf. cntrl fuel/air metering 3. P-3999 no DTC definition found, see srvc man. So, here is what I have. I think that p-1193 is the oxy. sensor downstream. I also think that the P-0326 is the oxy. sensor upstream. I have no idea what P3999 is.... So, am I right about the first two codes and does anyone have any idea about the p3999 code? If I am right about the first two is there anything other than replacing the O2 sensors that I need to do? Also, there is a "knock" on Bank one in the engine. It is not a lifter. Sounds like fuel/air mixture is the cause, but not sure. Any advice would be greatly appreciated!!!! Thanks, Norman | ||
