ok hope u guys can help ive noticed a couple of times, it feels like the car doesnt know wot to do when am cruzin or floorin it, it gets the power for about 0.1sec cuts off then on the off, and then on, like its not gettin enough desiel or the turbo cant make its mind up after i hammer it its ok for a while then it comes back when cruzin, i only use shell and have just noticed this over the past month or so, also noticed sometimes when i turn off the engine the engine management wants to come on but doesnt, last time this happened it came on when divin and good old "limp mode" kicked in
