I have been having a bad miss since I took my car out after sitting for the winter. Rough Ideal, power loss,stalling..ect. I have changed the plugs, wires, cap, and rotor. I have also checked my timing and fuel pressure. Still having the same problem? I plan on changing my ign coil which could be the possible problem, I have just noticed it arching from the terminal on the MSD Blaster coil. The arch travels from the termial under the coil wire boot and tracks about1 1 1/4" until it finds a ground. Really strange, has anyone ever seen that happen before??? Hope replacing that is my fix, if not I will do a compression test on all my cylinders.. Any advice would be great..thanks

 

Sounds like one of the piston rings are stuck.

 

I am having the same exact problem man and I have changed all of what you have and more. The only thing I can think to do now is change the 02 sensor and test the injectors.

 

I'm leaning towards my problem being a bad ignition coil....
