My Audi A4 is experiencing jerking and misfires, and I suspect it's due to faulty coil packs. How can I troubleshoot and fix this issue?
ReplyOne possible solution is to check the resistance of each coil pack with a multimeter and replace any that have readings outside of the specified range.
If the coil packs are fine, the problem may lie with the spark plugs or fuel injectors. I recommend getting those checked as well.
