Alright. Whenever I run my car at WOT, every second of two it will hesitate or stutters. I doesn't do it on take off ,or 50% throttle, or even %90 open throttle. Only when its %100 open. I though it was bad gas, but I changed from shell to conoco and it still does it. I just changed my plugs and wires less than 3 months ago. I'm also no throwing any codes. The only thing I've done so far is a MAC cai, LTs, and a canned Diablo Sports predator tune.

I don't really think it's a misfire, or I'm pretty sure I'd feel it all the time or at least whenever I accelerate. But I'm not sure whatelse it could be. ANy help would be great.
