Yeah taking the honey combs out is a horrible idea. Yeah your problem could be a number of different things, did you do anything to the car lately or did it just start up? btw how much boost are you running on the stock injectors? And with a 255 you really should get a fpr. You really would have a decent setup if you just got the rest of your supporting mods (which aren't much) to complete it then you could turn boost up safely. Just get injectors (550cc would be fine), a fuel pressure regulator, some sort of fuel management (safc is just fine).
