Misfire appears a few minutes after starting the engine

[Cyder]

I've been away on holiday for a week and before I went away the zed was running fine.

On getting home yesterday I took it out for a drive, started the engine and drove down the road gently, by the time I had reached the end of our estate it was lightly misfiring, thinking it maybe just needed blowing out a bit I took it down the main road and then the check engine light started flashing so I headed home.

When I got home I checked the code and got the really helpful P0300 code.

 

I started the car again this morning on the drive and it ran fine for a minute or so then started missing a bit, which was more noticeable if I revved it a bit.

 

Can anyone help as to why it would run normally for a minute then start behaving like this?

 

I'm thinking of chucking some injector cleaner in it as a starting point to see if it's related to those, I don't know when the plugs were last changed (must be at least a year/5000miles ago), but I'm a bit perplexed and frankly not very clued up with the engine side of things.

Have you checked your spark plugs and when did you replace them?

 

From personal experience i'd check and replace the plugs prior to anything, much cheaper than injectors

Turned out to be a coil pack that needed replacing, I had the plugs done at the same time. It's amazing how much better the car runs when all 6 cylinders are firing.

Seems be quite a few Z's with coil packs breaking down ATM. (Mine included).
