splutters

hi all new on here, my car is cutting out and sounds like its running on 3 cylinders when i go under 1/4 tank of fuel? my send on its way out? uprated internal fuel pump fitted wrong? spec is gt28rs with all trimmings and fully forged thanks

hi there people i went to overtake a car last nite in my seat leon cupra r and the power died, there was no smoke so isnt the turbo but wen i am about to hit boost it splutters but i can still here the turbo spooling and it still dumps... the car now will not go over 3k revs and if i try it...

Does anyone have any experience with spluttery engines on the LCR? My one is a bit spluttery at the minute on start-up and when i'm driving along...! I'm a bit miffed really. Do you think that it could be something to do with the plugs not sparking properly? Cheers!!
