I did plugs and coils, based on what the dealer said. It did fix anything. I was disgusted and scrolling videos when I watched yours. I put a new o2 sensor in and light is out idles perfectly! THANK YOU.

you sir are awesome!!! i never would have given an o2 sensor a 2nd thought to make it misfire.. after using this video as a guideline, i was able to find with my scan tool the misfire cylinders, and when i saw they were 1,3,5. bank against fire wall 2015 caravan, i thoguht maybe a bad head as i already replaced the 2,4,6 front head.. so after i completly reset the codes, fuel trim etc. and it defaulted to factory setting the van ran great no misfires. etc.. then after a short while about 15 min running / driving. came back and check engine code etc. so at that point i was convinced it was not mechanical like the head and had to be fuel being cut off or spark being cut off etc. so i proceeded to replace the upstream o2 sensor and now running perfect. thanks for sharing this video.

Literally the same symptoms with bank 1 happened with our 2014 town and country. Swapped plugs and coils with bank 2 and replaced upstream and downstream o2 sensor on bank 1. The problem is now resolved and I also used the bosch sensors. I thought the same thing with the design of the bosch sensors

@@ROCKETMANN56 long block or short block engine? Or used? Your old cylinder heads could cause misfires if not properly rebuilt. Does it still have the stock catalyst on both sides? (Do they both look like they came from the same manufacturer) maybe something to ask your mechanic😉Best of luck to you finding your misfire issue! Btw, the harness is about a $2K part and hard to get to-maybe look into that as a last resort.

Hey bud! Thanks for this video, I am getting p0303 and p0305 cylinder 3 and 5 misfire code on my 2012 Jeep Grand Cherokee 3.5L V6 pentastar, changed all the plugs and ignition coil for cylinder 3 and cylinder 5, engine light comes on again after driving for 15-20 mins with same codes, What should be the next step, O2 sensor or one of my mechanic said it may be Camshaft, lifter and rockers but it drives without any shakes or vibration and there is a very minor rough idle when I do a cold start, can it be the camshaft? Any help would be appreciated man!

The engine is noise on top? This engine 3.6 is common get damage the rocker arms. If is making noise you neeed to remove the valve cover and inspection the camshaft. It can be also the engine in cylinder 3 have exhaust valve burn. And is losing compression from the valves.

Code scan on autozone shows spark plug / Coils but like stated they have been replaced

Sometimes certain manufactures self diagnoses maybe unreliable (in rare cases) male sure you're on the proper bank at the proper cylinder. Number 3 seems to be on passenger side bank in the middle on this truck. Try pulling all the plugs and inspecting them well while looking abnormalities in oddities with the outliers. Like fouling or damage plug. Try swapping plugs And coils to opposite bank to see if the misfire move. Check valve train...

@@partsshooter so even after replacing all 6 spark plugs and coils, Even tho missfire is just for cylinder 3, i should swap the coils around?
@partsshooter Жыл бұрын
@jhonGze I understand You now. This only get more complex from here. You'll need to check for powers and ground at cylinder 3 with injector and ignition. You'll have to pull things down so you can test injector circuit. Easiest way without having high tech equipment is using a multi meter and test light. Compare values with a working cylinder. Example, cylinder 1 works. See if with key on engine off you have same voltage or ohm value at same wires.

I have a 2015 Grand Cherokee that now has a PO305 code and shakes at low RPM and sometimes bucks during acceleration. I am preparing to change the plugs and coil packs.

I need data info from your engine computer, such as fuel trims and o2 sensor operation. Your testing procedure with the isolated issue, what was tested, and how. Any other work completed etc. These cars aren't simple. If you don't have at least a bidirectional scan tool or scanner that gives live data, I can't help you.
