Before I tore my car apart this winter, same exact thing. EXACT. I was told several times it was the opti gone bad. I will be replacing it with the MSD 6BTM though, so I hope I do not have the same problem. HOPE key word

 

well i repaced teh plugs but not wires, could wires be causing this, and if it matters the stumbling once it starts just gets worse and worse, this is annoying the hell outta me
