Okay boys, I've changed out about 6 of these coil packs since I've gotten the LR. It runs super smooth. But it was sputtering last week and now it's really bad. I read the codes and it said ignition coil packs A and B along with cylinder misfires on 2,3,5,6. I reset and read again. This time it said packs A,B,D,F and G, along with a misfire on cylinder 6. Im now concerned that it's not just coil packs but a bigger issue? It never showed ignition coil groups before.
