i also asked to talk the tech and he happened to be out too. I got joopedthe last time I had it at another dealer for the same issue..they ended up taking out the injectors and testing them..then asked to do a head removal to test valves for another 400. When in all this procedure that I requested be done they go ahead and do their own thing. I feel like a pricked but I'm treading water here with this dealership too.
