They are connected right ... Driver side to passenger side . Passenger to driver side just did valve adjusment again an it still having a problem . Dnt wanna idle I keep needle steady at 2500 an in couple sec needle starts to drop wit out letting go of the pedal like if somthing cuts off then goes bak up to normal at steady 2500 rpms

The fronts are run normally; driver to driver and passenger to passenger.
Again, your O2's are wrong. I found this out when I repinned my PCM so the rear O2 ports would read as the fronts, allowing me to simply use 2 sensors, plugged into the rear. The rears do indeed cross, and I didn't know that. I had the same symptoms you did. P0300 and a completely fouled out passenger bank of spark plugs.
Swapped them so the driver O2 bung on the header was plugged into the passenger, and the problem was solved.
