so ive had this problem where around 4000 rpm my car starts to cut... replaced the dist. and tfi an it still did it... new plugs an timing at 12 degrees an it still does it.. well lastnight i think i might have found the problem!!! i popped my hood an seen all of my plug wires arcing at random spots in the wire an my msd coil looked like it was putting on a fireworks show at the bottom!!! I dont think its suppose to be doing this at the coil??? is an msd blaster worth the money?? ive got a jegs knock of version of it right now...
