Hello all, I am new to the Explorer forum.. I was wondering if someone can give me some advice..I am getting a P0300 code.I changed the plugs, wires and coil pack..Still misfiring..The engine is the 4.0...I checked the vacuum and im getting a rather erratic reading which I will try to post..I sprayed carb cleaner around the intake with no noticeable difference in Rpms..Is there any known sensors that could cause this condition?..My friend seems to think its the injectors but I find it hard to believe multiple injectors would go at same time..I appreciate any advice or help...Thanks so much
