error codes P0351,352,353

Have replaced the ignition coil pack on my 2002 jeep wrangler sahara, automatic transmission, three times.
Is there something else that would cause these error codes. Or should I replace the ignition coil pack again?

In my jeep there is a coil pack of three individual coils. Two for each of the 6 cylinders. There aren't any individual wires that I can see. Only electrical connection is at the rear/firewall side of the coil pack.

It is likely the rail or connections but Did you cover the basics?
how are the plugs? The boots? And is the rail torqued properly?
When you changed the other rails are you certain they were bad?

Guys, Pulled the ignition coil off again. New one will be in on Monday.
Have replaced the CCV, only $5.00.
Pulled the spark plugs and they were AP985 which had a TBS on them. I ordered APP985's which are the dual platinum plugs. They will also be in on Monday.
Have added concentrated fuel injector cleaner.
Thanks for all of your advice and come Monday I should have an update on my TJ's status.

Most recommend good 'ol Champion Truck plugs, save your money on the fancy ones.
