Thanks mate, i have checked that the leads are in the correct order now but now i need a good explanation on why the engine had a ruff idle and had clean fast acceleration now after changing the spark plugs and leads now has a clean idle and an interrupted (dirty) acceleration.
the reason for the twin coil pack is for each compensating cylinder, when one cylinder is at TDC sparking (9-10volts) on the power stroke its compensating cylinder is also up and sparking on the exhaust stroke (3-4volts) to burn any unburnt fuel, so if its compensating plug is damaged or not correctly gaped 2 cylinders with not fire or misfire causing rough idle, hope this might help if not other possibilities clean throttle body, change trans fluid and filter, check fuel
