Intermittent ignition coil is common on the 4.0L I had one that would buck and surge and not even set a Check Engine Light identifying which coil was failing. Some shops just replace all coils if it doesn't identify which coil has failed and a drivability problem is experienced.

I have a 2000 S-Type and I am experiencing the same problems. However, I am replaced the damaged engine coils and I'm still having the same problems with miss-fires. A mechanic said it all 4 timing chains need to be replaced at an astronomical price. Do you have any suggestions/advice?
