hi there. i have a 1.6 16v which most of the time runs perfectly fine then all of a sudden it decides to only run on either 2 or 3 cylinders. this could be when i first turn the key or while out on a run. if its when i first start it then it is very difficult to start and takes 4 or 5 attempts of it just turning over to even try and fire. i haven't started looking at anything at the moment i am just wondering if anyone has any ideas before i waste a load of time and money testing and changing the wrong parts
