i get a flashing check engine light once in a while but its steady the rest of the time. i go-t the codes for a random misfire and also for a misfire on each cylinder!! i replaced the spark plugs and i ordered new plug wires that should be here wednesday. what else could be the problem? by the way its a duratec and the plugs were bosch dbl plats. and my car has 90K (1998 SE)
TIA
