hey there, just wondering if anybody can help me out ?? i have a series 2 rs4. Once the car reaches operating temp on my way to work, the malfunction light comes on, i give it a rev and the light goes off and stays off, approx 45 km's to work. Very rarely does this happen on the way home in arvo.. nissan checked the code and told me most likely a coil fault. Since then i have fitted splitfires and new sparkplugs but still no difference. The car seems to be running fine and i can't notice any misfiring ?? any ideas would be much appreciated !! THANX
