DaisyDukes Posted May 21 Report Share Posted May 21 (edited) Hello everyone. This is a great forum with lots of great info. Figured I’d give it a shot. 2.4L has cel for cylinder 3 misfire. I have been reading bout this issue so here goes 2015 Dodge Journey crossroad 2.4L past 2 weeks all new coil packs and spark plugs changed out twice 1st. set was Champion plugs/carquest premium coils. Pre-gapped but double checked 2nd. set was ngk plus/ngk coils. Pre-gapped but still double check reset engine light both times. Would drive good for a day then after a sit, when we start it there’s a rough idle for about 15-30 seconds then car drives fine but has cel for cylinder 3. 3rd. Compression test great. Replaced all fuel injectors and rail. Checked wiring and grounds. Also went ahead and had valve cover gasket replaced. Drove great for about 2 days. Come outside to start her up and boom there goes the rough idle once again followed by cel 4th. Replaced manifold gasket and pvc valve. Drove good for about a day. Then issue right back Today. Vacuum leak test. No leaks detected. Car history. 1 owner car, 156k miles superior on the maintenance. Never ran hot. any ideas out there??

John/Horace Posted May 23 Report Share Posted May 23 Wow sounds frustrating. You have covered pretty much all the bases. A node light clips on the injector wire harness and flashes to show a good strong constant signal to the injector. When engine is acting up it needs to be used on your wire harness. If it shows an issue in your case It would probably indicate an ecm computer problem. Not a common failure item and not cheap to replace. Remanufactured units are available.

Dean H Posted May 25 Report Share Posted May 25 One thing, that is a problem on the Journey. There isn't enough engine to chassis ground straps or cables. The main engine battery ground is a small 4 gauge. Should go to a 2 gauge. Add a 4 gauge ground on the opposite engine mount. 2 gauge if it will fit in.
