HI if a compression test on cyl 3 is fine ,the next step check coil pack if independent coil swop with a functioning cyl (eg 2 ) ,If this repairs the problem coil should be changed.Do check wires connecting to coil for continuity on power and ground supply.In some rare cases the above answers are over powered by a faulty ignition module .

2004 Sorento began with code P0305, cyl #5 misfire. Inspected and replaced plugs, wires, and coil pack on cyl #2. Repair shop told me cyl #5 injector bad so they replaced. Still has misfire.I suggeste


If you had code P0305, I don't know why they would have done anything to the #2 cylinder but if they have already replaced the plugs, wires and injector; here are a few more items to check:
1) Check connections from ECM. Look for any corrosions or bent/broken pins.
2) Check the fuel line pressure
3) Check the engine compression
4) And if the above are good, then you will probably have a defective ECM

PO302 cyl 2. etc. get the code find the correct cyl. unplug little connector u will need a 7mm socket to remove the bolt holding the coil in place then pull up on the coil and boot.... if u have plug wires get the code find correct cyl and follow plug wire to coil pack in front of engine there will be two one on each side in front of engine...

Sport Wrangler 6 cyl. Engine lite flashing. Diagnostic tool lists code PO305. I looked it up and it states misfire in cyl #3 & 5. How do I fix this?


Check the plugs, wires and coil pack for these two cylinders. Most lilkely it is the coil pack, they work for 2 cyclinders at a time. cylinder motors use 3 and 8 cyl moters use 4 of these. If your und=sure where the coil pack is, follow it backwards from the spark plugs.

Mis fires have changed spark plugs spark plug wires and ignition control module


Please describe miss fire? or do you mean it has a miss? cross fire occurs when plugs are firing before or after they are supposed to if it's missing then that's another issue could you please give more detail?

You are mis fireing on cyl 1 and 3 if you replaced plugs and wires and coil this is going to be a fuel injector issue or valve issue. See if you can swap the injectors with known good cyl. and see if it changes. Or have a shop do a fuel injector service on it to see if it helps. It may be to late for the fuel injector service.
