A few months back i had engine misfiring on the number 3 cylinder. I replaced the ignition control module and the number 3 ignition coil. The check engine light is off. But when the car is cold it runs fine, as soon as the car warms up, when i accelerate from second gear to third etc.. the engine starts studering or pulling. What can be the problem now? Also how can i check if the other ignition coils are bad?
