Hi guys i need a little help to figure out what is wrong with my car. I have a 2001 Lupo gti. When i start it car up its like the car wants to cut out and it sounds a bit lumpy. When giving it a rev the revs seem to go up slower than they should. Once the car is warmed up it runs fine but when driving and putting the foot down the power isnt what it should be. Sometimes i get a bit of power coming in and out and then it goes back to how it was. Anyone got any ideas?? Thanks in advance Gary
