if you can get to the plugs while the vehicle you could always try pulling the plug wire off the spark plug (cardocs good for the heart method) to see if the engine changes sound. if it dose that cylinder is working if the engine dosen't make a change the cylinder is dead (not working). if 3 and 4 are not changeing the engine it might be time for a coil pack.


as far as the loss of power heres an example if one cylinder is dead on a four cylinder engine you lose about half the engines power.
