Just wondering if anyone has seen this? I tried a search, and all seemed related to either idle or 5200. The car will hestitate, and then accelerate, hesitate again about 300-400 rpms later, and repeat. It will hit about 7K, but doesn't like to go there. I'm guessing it's a fuel problem, and haven't tried it a part throttle yet, but wanted to see if anyone had seen this before?

I have this same problem right now with my Turbo II... For sure its fuel problem, you need more fuel like me...!
