I understand.
Still need to know which engine setup you have.
Look at the VIN number. I need the 8th digit. IT will be either an '8', 'G', or a 'B'...
Which one do you have?
P2305-IGNITION COIL #2 SECONDARY CIRCUIT-INSUFFICIENT IONIZATION.
Start with removing the cylinder #2 plug wire, and measure resistance from end to end. It should be less than 10,000 Ohms.
Let me know what you find.
Hello, my name is Kevin.
I hope this answer helps you. Your complete satisfaction is my goal. If the answer is not clear, please reply and I will assist you more.
I have run across this one before.
After a series of tests including everything that you have mentioned, I wound up replace the engine coil capacitor. This is not something that normally goes bad, but on the vehicle I was working on, it was the fix.
Hope it is the same fix for yours as well.

I found the answer by working at it; & yes they should know.
They should also know to call the tech center when the are stumped & not just throw parts at a car if they are testing as good.
Anyway, as I stated before, this is what fixed the problem on the pt cruiser that I was working on with this same code.
I did not replace anything but the wires & plugs on the vehicle that I worked on. The processor was not in question & the coil packs were doing there job.
The problem was improper ionization which can be caused by a lack of power (coil pack) or bad ground. Those two items were good as well as all the other components.
So an engineer & I put or noodles to the task & decided the capacitor was bad & replaced it. It fixed the concern.
