I have a 90 nissan 300zx . I am new to the nissan 300zx's. I recently bought the car and run good when I got it but when I'm going down the road sometimes it will just cut off on demand but will crank right back up and run fine. Also like it is sluggish until it gets past 3000 rpm when taking off. But after that she runs like a bat out of hell. What in the world is going on to loose power like that PLEASE HELP!!!!!!!!
