Its the coil or the the coilpack harness wires, While your at it, check the part of the wiring harness that goes to your cam position sensor, it going faulty can cause this code.
P2302 ignition coil #1 secondary circuit, insufficient ionization.
This will occur if the PCM (Power Control Module), detects that the secondary ignition burn time is incorrect or not present.
The most common possible causes are faulty spark plugs, ignition wires or ignition coils.
Hope this helps.
I have replaced all plugs ,wires and coil still getting code and car still runs rough, any other sugestions to follow?
Ive replaced cam sensor ,crank sensor,all plugs, all coil packs, PCMmodual and code still there i have to keep the #1coil pack unploged , the plug eire that goes to cyl. 6 and the plug to coil or it melts the #1 coil quick if you can help that would be great thanks
I haven't participated in these forums in a while and just a fluke I saw this but it caught my interest. I haven't participated in these forums in a while and just a fluke I saw this but it caught my interest. My first question is, did you replace the wires as well? I ask because you have plugs listed but no wires and one should never make an assumption.
Assuming you did I would recheck everything again, for both installation as well as correct replacement part."New does not always mean correct or good". Pull the wires, coils and plugs and visually reinspect everything. Make sure there is nothing too close that could cause a short. I would also check the PCM plugs for any signs of corrosion. I just fixed an issue with a 2004 dodge that traced back to corrosion on a couple of the PCM plugs. You also need to recheck the cam sensor as well. I have seen issues similar to yours that were caused by the sensor becoming loose after a recent replacement. Also if anything was repaired recently before your problem, check that all fuses are correct for it's use. An incorrect fuse in the ASD relay could hurt a PCM and if not changed would do the same for the replacement.
If everything checks out and you eliminate the obvious.......
Time for a trip to "Outer Limits" school of automotive repair. This is a long shot but a loose timing chain can allow cam and crank sensors to become out of sync or unrecognized. The PCM needs precise signals.
Not sure if any of this helps but good luck.

Good morning.
Check all connections if fault does not clear move no 1 coil to no 2 and see if fault follow s if out does replace coil.

But when I put my old ecm back on the shaking and misfire goes away, I still have the original problem of it not shifting
