So I haven't driven my e46 330 all winter (although unfortunately my new garage isn't finished yet so it had to sit outside) and just fired it up and to my dispair it wasn't running as smoothly as it did last time.. The idle was rough going up and down so I read the diagnostic codes which said misfire cylinder 3, 4, 5 and also Fuel Control mixture.

So I just ordered some new sparkplugs (NGK) but what else should I check?

Thanks in advance,
