i wonder what i did with that spare ICM i had??

 

probably is the ICM. they usually go bad around the same time as the coil.

 

oops, sorry, double post.

 

take the cap off the distrubitor and check the rotor i too also had this problem and after a couple trips with the tow truck i finally figured out what was wrong. it was the rotor that gets lose there should be a hex head screw on the shaft and mine came out because of the vibration so i put the screw back in and everything worked fine agian and i had tried everything and u can still have spark because the rotor is still spinning just it isnt puttting off spark at the right times giving you a misfire which leads to fouled plugs

 

maybe the module inside the distributer, not sure what its called
