tipplerty Posted October 5, 2019 Report Share Posted October 5, 2019 (edited) Hi Everyone, I own a 2009 Dodge Journey 2.4L. My check engine light came on about a week ago and after a couple days it started flashing and the engine throttle down (barely do 40-50km/h). I was close to home so I limped it back home. I had a friend come over with a code reader and it was giving us random misfire codes and crankshaft position sensor codes. So I bought a new crankshaft position sensor and replaced it. When starting the vehicle the check engine light was still on, the engine seemed to start normally and then after about 30-60 seconds the check engine light would start flashing again and the engine would throttle down and start shaking. While the engine was shaking we pulled the wires from each coil pack one by one with the following results: (Right to Left) Coil Pack 4 - Engine would die out Coil Pack 3 - Engine would die out Coil Pack 2 - Engine would die out Coil Pack 1 - No change - engine still running We assumed that Coil Pack 1 was the problem, so I bought a new one and replaced it. After replacing, still have the same issue. Did not have the code reader at this time, so we figured that maybe the codes needed to be deleted and that may solve the issue. Had my friend with the code reader over today and checked the codes before deleting them and only got 2: P0300 - Random Misfire Detected P2302 - Ignition Coil "A" Secondary Circuit We deleted the codes and the issue still remains. Start engine, check engine light is on, after 30-60 seconds it starts flashing and then the engine throttles down and starts shaking. (Appears to be running fine when first starting) Got to thinking and tried the following: While engine is throttled down/shaking, pulled wires on Coil Pack 1 and same as before, No change - engine still running, so I thought hmmmmm guess the coil pack may not have been the issue cause its still doing the same thing. So I got to thinking, i'm gonna try this when I first start the engine and it's running properly before being throttled/shaking. So when I pull the wire from coil pack 1 right after starting, the engine dies out. So it seems that the coil pack is working or receiving power before the engine light starts flashing but does not seem to be receiving power after because when I pull the wire after, it has no effect on the throttled/shaking engine. So I am at a loss now as to what to try. Any ideas? Any help is much appreciated! Thanks!

2late4u Posted October 5, 2019 Report Share Posted October 5, 2019 check all the wiring going to that coil pack and inside the connectors to see if there is a short or bad wire somewhere that is what happened yrs ago to my daughters van they kept replacing the coils till one of the mechs caught it the connector where they plug together was shorting out sometimes it would run good for a week and then go bad they replace the connector and that fixed the problem Quote Link to comment Share on other sites More sharing options...

tipplerty Posted May 10, 2020 Author Report Share Posted May 10, 2020 Hi All! Sorry I did not update this when I resolved the issue. I totally forgot! I took it into a mechanic and it turned out to be the wrong spark plugs!! I had the spark plugs changed almost a year before the problems occurred and the person that changed them, used the wrong ones. The spark plug gap was bigger and the ground electrode (ground wire) was actually arcing on the piston and didn't cause issues until much later. I suggest you triple check them and make sure they are the correct ones. 2late4u and jkeaton 2 Quote Link to comment Share on other sites More sharing options...
