    Recently my 03 cobra has been feeling off, a little sluggish, harder to start and when im cruising in 1st of 2nd gear(Stop sign to stop sign), it will occasionally miss and ill feel the car kind of..lurch. I did a small data log just to get an idea and im mostly clueless at what im looking for...but i did notice that my "Pressure drop across injectors" is very volatile..to me it would seem that since i was at a steady acceleration, the pressure drop would be fairly similar. Thoughts? (I've also uploaded the data log if you want to view it in live link)

    without looking at the log or graph my first assumption would be a weak fuel pump
