Couple of things u wanna look at.. Your plug wires.. should be at least 7.5mm i'd run 8.5 or 8.0 but 7.5 will do, Secondly take a look at your timing buddy.. make sure the cams are lined up correct in the "up" position take a wrench and bring it to TDC and line it up thirdly check your igitior and coil.. Its one of those things i promise i had the same problem but it was my coil and what not but if ur timing is off man, your car could be in some serious trouble.. hope that works.
