My car has developed the ignition coils problem. It starts and runs normally from cold until it gets warm then the toxic fume and check injection warning lights appear. The engine then seems to misfire at low revs sometimes stalling on tickover and then ticking over correctly after a short while. I have replaced all 4 spark plugs and all 4 ignition coils yet it is still doing it. Do i have to disconnect the battery to clear the fault or is it something else?
