Isthat a problemin the coil oranybody ele havea idea. couldit be a ground problem????

 

Battery disconnected seems to be "normal" if the battery has been removed, dead, or is otherwise failing. That code stays in the system for something like 20-50 cycles.

The coil or distributor is a common source of "multi-cylinder misfires". You mentioned that there is power going to it, but didn't mention if your plugs were firing properly.

Also, It would be good to know what engine you have (2.0, 2.4, 2.5v6) and any other symptoms (running rough, pinging noises, knocking, etc...)
