danm dude, may want to learn to speak and type proper before you do any work on a car. i barely understood what that said. try checking your plugs to see how they are.

 

Holy crap, that was the hardest thing to comprehend. What the hell are you talking about? Thanks for the headache

 

When my ICM went I was going down the highway and the car just died. It would crank, but wouldn't fire.
