Well I change the two relay 614 and nothing change. Same thing happen. When I reset the dtc.... the car run smoother........but it take only a short drive and the car make a lot of missfire. The missfire happen only on the 1 to 4 side of the engine. I will post the missfire count tomorrow. A lot of missfire came from cylinder 1 to 3. So I decide to swap coil from cylinder 5-8 and nothing change. Any other Idea folks ? I'm a little bit disappointed

My pcv valve failed and this caused a slight misfire on my engine...
