Ok so a little background. First im newish here. I have a 2007 jeep grand cherokee 4.7l v8.
It has roughly 145k miles. For the past couple weeks it has been idling rough, hesitating on acceleration, misfiring etc. Now it only does this in the afternoon when the outside temp is hot. Morning time i can start it up run it no problems.
The codes that pop up are p0300 random misfire, p0202, p0204, p0206 (injector circuit open # 2 4 and 6) and most recently p2314.
Things i have done/troubleshot:
Fuel pressure is good around 55-60.
All injectors measure within the resistance and "click"
Spark plugs changed less then 1k miles ago.
Egr valve changed (broke connector off it).
Battery and alternator are good. Fuses all check out.
Anyone have any ideas?
