2004 ec300 cdi

[yowie05]

i am in need of a CDI for a 2004 EC300, dont suppose anyone has 1 laying around gathering dust? im sure a 2005 will work but the plugs are different. ive got an intermittent spark problem where ive got spark on 1 kick cycle but the next 10 i dont. i tried running earth wire from engine to coil thinking it may be a bad earth. Stator tests to factory specs its not the coil either as im using a different coil and getting same results
