   Hi,
   I had my furio converted to a 16v today and it has now started to missfire. The coil pack has been changed and crank sensor. Also has a full service. It also doesnt seem to have alot of power untill it hits 5000 revs. Could someone please tell me what it is?
   
   Thanks in advance

   Its decated, would the lambda cause this?
   
   It pulls upto 5000 then it feels like vtec and really launch you back in the seat, it holds back all threw until 5000 no matter what gear your in.
