Ok too clarify it does it when you really nail after second gear. If you get up to speed gradually, no problem. I was going to change the plugs & fuel filter just as a start but it is pouring out today. The only other symptom is at the top end of any gear (let's say 4800-5100 rpm) the car does begin to break up almost as if it had a rev limiter type of thing. But I would usually shift well before that high of an RPM anyway so I havn't really worried about that part of it, but I am guessing it is related. I am also running a stock fuel pump as well...
