Question about 2004 Dodge Stratus
Coil and spark plugs and wires
See if you are getting spark to that plug, just stick an old plug in the boot and ground the plug to metal on the engine and crank it

Who is doing the parts replacing?
Have you looked at Scan Tool Data & road tested?
Have you actually done any testing, to find a problem
& used the codes to component test
Till you answer that, I will say you need a repair shop
Lots of things cause misfires
Changing spark plugs & a coil or two ,based on a code,
is not doing the required testing to find a problem or the
need for parts just yet

Here's a link to the firing order including a diagram: It's 1-2-3-4-5-6 Clockwise
Hope this answers your question. All the best!

SOURCE: CODES P0300 P0303
These codes are codes regarding failure. The code P0300 means repeated Engine Misfiring. The code P0303 means Repeated Misfiring of Cylinder Number 3.
Kindly contact a technician to get both checked. Their Heads must have been misplaced or broken due to misfiring.
Thank you sir, Have a nice day.

SOURCE: code p2305 ignition coil b
The wire for the secondary on that particular circuit has to be tested If you have a ICM that secondary has to be tested there, If it is controlled from ECM it has to be tested at the ECM, because its a secondary wire it is capable of shorting the ICM or ECM it self, you only listed the year and.no engine size.

Ouch! A case of the raucous rodent! I've been there...Not fun trying to track down and repair all the damage.
First of all, let me explain how the code sets: The computer monitors the PRIMARY side of the coil to determine the burn time on the SECONDARY side of the coil. This can be a little confusing. The code will set when the computer determines that secondary ionization (burn time) was too short, too long, or did not occur at all.
If you have confirmed that there is no spark at the spark plug wires, then that is why the code is setting...ionization is not occurring at all. What can be a little confusing is that this can be caused by a failure in the PRIMARY coil circuit even though the code is indicating that the computer is having a problem with the SECONDARY circuit. (The secondary circuit can malfunction even though the primary side is functioning perfectly, but if the primary side malfunctions, the secondary side ALSO malfunctions - it is impossible for the secondary side to work if the primary side is not working.)
So, I said all that to tell you this: I think you have pretty much eliminated the entire secondary side of the ignition by replacing the whole circuit. So the problem must be on the primary side. (Probably more chewed wires)
There are 4 wires going to your ignition coil. The BROWN/WHITE wire comes from the ASD RElay and supplies battery voltage to the coil assembly. Since the other four cylinders are firing, This wire has to be OK.
The code you are getting is for coil #2. This coil is controlled by computer through the DARK BLUE/TAN wire. If you disconnect your coil connector and probe this wire with a test light connected to the POSITIVE battery post, it should "blink" when to crank the engine over. My guess is that it will not be blinking. You can do this also on the BROWN/ORANGE (coil #1) wire and the DARK BLUE/DARK GREEN (coil #3) wire to see the difference.
Anyway, if the DARK BLUE/TAN wire does not blink, then the wire is broken (chewed?) between the coil and the PCM.
