I have a 2004 Durango 5.7 L Hemi. The check engine light came on and I opened the hood to find that 3 of the 8 ignition coils were busted open. I had noticed a loss of power prior to this happening and was close to changing spark plugs and wires. So I got 3 new ignition coils, new wires and new boots for all the coils. (and of course new plugs) I installed all. After firing up the engine was running worse than ever. I got the codes P 2302, p 2305, 2308, 2311, and 2320. (coil secondary circ.) Also another coil popped open on my test drive. Can anybody help????

 

Look at the TPS as it may need changed,

You may want to recheck the plugs, wires, and coil packs to make sure that they are being read by the ECM
