[Kameron1]

Hi guys im in real need of help . i drive a 2006 citi golf 1.4 carb , my problem is as im driving the dash goes completely off rev counter , speedo indicators etc however the headlights work and radio. i did have the fuses near the battery checked and tested they are both still working. im not sure where the problem lies whenever i come to a stop with both clutch and brake in at the same time everything comes back to normal. then starts again as i take off. the problem does go away after a while but then starts again. please help
