Hey guys, I have a 2014 Dodge Journey. When I first start up this beast (I have nothing on at the start) I have a rough start (SUV shakes, engine sounds rough) this only lasts for about 20 seconds. Then the shaking stops, and everything runs very smoothly. That point I turn on a/c or heater.
I have changed the plugs about 3 weeks ago, I also get that P301 code so I changed the coil in #1. Even tried swapping the new coil in a different spot. Nothing seems to make a difference.
Anyone with any tips ?
Thanks
