Zafira 1.6 petrol ('05 plate) - Fault Codes 0300 & 0303 Zafira - Julian

Using the 'pedal' system to find fault codes the following are on my Zafira. Very jumpy when driving and 'engine' warning light occasionally coming on and flashing.

Is this just spark plugs?

Could it be EGR valave? if so, where is it on my car?

Help please.

P0300 multiple miss fire.

P0303 cylinder 3 miss fire .

Could just be the plugs, or could also be the coil pack.

Really though, you need to get it properly diagnosed. The pedal trick is ok as a quick fault find guide, but ultimately a proper diagnostic reader should steer you in the more specific direction.
