Disco 1996, got code 1362 and cyl 8 misfired. I swapped 2 coils, and got same problem. It seems that it implies it is not a coil issue. Could this code 1362 indicate a wire or spark plug issue? It seems to imply a more complicated issue, pre-coil.

 

Well not only are you guessing and wasting money, throwing parts at it but you might, in the future post in the D1 section so I don't have to move your thread again.
As for that misfire, you always start with 8 mm plugs and wires, make sure you are burning 91 plus octane and do an induction cleaning.
By the way, hold on to those old coils, they are still good.

 

mike- thanks for input - I have swapped coils a few times, so I had spare ones. The truck has been running fine for 50K miles. swapping 2 of the 4 coils with each other did not help: I got the same 1362 code. I was hoping that the code would follow the "bad coil", but since the same code came back, I agree it is not the coil. Could that code just mean that I have spark plugs or wire problems? These are fairly new, maybe 10-15K miles. Easy enough to replace the wire, but I hate to keep on guessing when I don't really understand what that code 1362 means.

 

seen quite a few ecus go bad, pull out the ecu to see if its rotted. if it is then buy a used one and get it coded at the dealer.
