I was driving my gtv and the engine management light came on - and the engine was running a bit rough. Stopped the car and it wouldnt start so called a tow truck. Waited for half an hour and the car started although with the engine light on. So drove home. When i got home the thing (not sure of technical name) which goes on one of the spark plugs had melted slightly. So i just ordered one and changed it. The car started and ran beautifully, smoother than before. Then engine management light came on again and the engine became rougher. Drove home stopped the car and it wouldnt start.
So let it cool down and it started. So heated it up again and the throttle blipped and the sound of a relay was heard. Stopped the car and it wouldnt start again. Then could hear a click of something like a relay after the car had cooled down and the car started. Wot is wrong with it - im desperate need my car for work - any help would be great thanks.
