First of what happens

Was headed home from doing some running around and she just died but came back(more like a surge)/
Than anything from 1/4 -3/4 throttle is dead but re-catches herself .. Timing and fuel pressure is good. Module is good tps is good but I did notice a burn pop mark (like. The one you see when a fuse blows) on top of the coil in the corner next to cylinder 6.. Also the actual could is slightly melted.. But I noticed the cap had wetness in the terminal groove under the cap. It is a hypertech performance cap and rotor... And sometimes she starts OK and idlea and other times Shea running on 7 or 6 cylinders .. But sometimes comes back....

I think that's the problem but won't know for sure if that is the problem. But maybe you guys can tell me.

 

Forgot to mention it has been all wet and raining the past week
