02 concorde lx p0300
 

i have a chrysler concorde lx 2.7l, with about 35,000 miles on it. i presently am getting a code p0300. my misfire data shows the miss only on bank 1 (1,3 and 5), i can feel a slight shake in the car at idle my fuel trim on b1 is at -22%, bank 2 is normal. the plugs, coil 3, b1/s1 o2 sensor and upper intake gasket are all new. i have looked at alldata wiring diagrams and there is nothing that i can see that would effect only b1 aswell i have not found any tsb's on this matter. this car is driving me and my boss crazy. i know there is something i am just not seeing or it's not registering. please give me a hand on this one.

time to look at the basics then misfire on all 3 clys one bank. are the coils even putting out spark? if not whats missing power or the ground pulse from the pcm?
I am gonna say U have a broken ASD power supply wire to the 1,3,5 bank.
