Aniforatos

So. I just bought myself a Forge Diverter Valve. It worked very well when it was installed. But today in the rain for some reason when I accelerate hard the car begins to get short losses of power. I immediately let off of the gas when this happened but tonight I tried to keep accelerating and my check engine light started blinking until I let off and the revs fell below 2 thousand. Any ideas pleeaaasseee?
