Got 2004 dodge stratus misfiring code says p2305 already changed coil and spark plugs and wires still misfiring


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

2004 dodge dakota in limp mode wont go past 2000 rpm P2305 code comes on check engine light comes on can reset code but light stays on and wont go past 2000 rpm


Since you didn't say what engine you have, I am assuming it to be a 3.7 L. Code P2305 is set for insufficient ionization of the #2 coil. 1. Inspect the spark plugs for correct application, these should have NGK platinum spark plugs installed. Inspect the plugs for any signs of misfiring, such as carbon tracking on the spark plug insulator or the coil boot. Inspect for cracked spark plugs or incorrect gap. Inspect for any kind of fouling on the spark plugs. Replace the spark plugs or the coils as needed.

2. Verify the wiring is not shorted to ground from the coils to the Powertrain Control Module (PCM).

3. Keep in mind that anything that can affect the air fuel mixture can cause this code to set. Be SURE that there are NO vacuum leaks, the injector is not at fault, etc. Moving parts one at a time (spark plug; coil; injector) to "known good" cylinders is the best way to diagnose this trouble code.

2004 Dodge Stratus 2.4 DOHC. Was misfiring and barely running. Code showed P0300, P2302, P2305, P0700. Found Coil Pack had a burned spot near the #2 wire and large crack between #2 & #3! Replaced Coil and...


Reminds me of when a friend of mine had a car with carbon tracks on the distributor cap. I wiped it clean and it worked perfectly. Are the plug cables going to the correct cylinders in the correct order? A hanes service manual actually put the wrong order down in a mustang manual.

Code p2305 ignition coil b secondary circuit. no spark from coil on 2 cyl. replace coil and spark plug wires found and fixed broken wires for remote start


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.

How are you... I have just bought a 2006 Dodge Magnum (2.7 liter V-6). I have a check engine light on and I am receiving 2 Codes with my Auto Scanner Plus. 1). P0300: Random/Multiple Cylinder Misfire...


that is the coil on top of #5 spark plug. you can replace the coil or switch it to another cylinder and see if you get a different code. misfire codes are 301-306.

What causes sputtering in the engine of a dodge neon, does it need a tune-up, cause I keep up on the engine maintenance?


those neons are known for the coil pack on top of the valve cover to get cracked, if that is the case it will arc from the spark plug wires!!!
when it gets dark go out under the hood with a spray bottle full of water and while the engine is running spray a little water all around the coil pack and where the spark plug wires connect to the coil pack!
then while you are doing this, watch for any sparking/arcing you'll know it when you see it it will look like electricity kinda like a mini lightning bolt!!!
