it could be a bad coil or something then. what plugs did you use? if they are new try swapping #3 with another cyl and see if the issues moves.

#1 cylinder is at the back of the motor. I think some carbon in the cylinder could have been knocked loose. Clear the code and see if the code reappears. If the code does reappear then pull the plug, make sure the plug has no cracks in it, that the plug is gapped correctly and clean it.

But with the I6 in the Grand Cherokee, I was certain that it was numbered from front to back. He seems certain that it is the other way 'round.

Yes, it is front to back on the I6 WJ. I've had enough problems with my cylinders misfiring last year to remember that one WELL. :)
