I've just got myself a 2005 Fiesta ST, it was serviced in April prior to buying.
Recently it is hard to start, you have to hold the key in the start position for a while until it fires. If you don't hold it long enough and stop starting the battery and oil lights are on but once it starts they're gone. She is going back to the garage on Tuesday to have this looked at.

That was just a bit of background story, when idling at traffic lights it will every now and then shudder as if it has missed a beat. I'm not sure if that is normal with a relatively powerful engine (I know its not powerful like a porsche but to me it is!) or a indication of something worse.

Any ideas welcome.

When the engine is cranking the battery and oil lights will be on as a) the battery is being discharged by the starter and b) engine cranking speed will probably not generate sufficient oil pressure to switch the light off. Once the engine is running under its own power then battery light goes off as the starter is no longer discharging the battery and idle speed will produce sufficient pressure to switch the oil pressure light off.

As for the shudder, that's not really a very good description. Was it like a misfire? More/less violent than a misfire?

I did think the warning lights would be something like that but felt I should mention it.

A lot less violent than a misfire, it's no noisier than it idling. Just can feel it, cars in neutral (obviously) but it just has a little shake. I'm filling her up with normal unleaded, what I've read say I don't need super.

Also I noticed when starting I need to depress the accelerator pedal to start.
Thinks makes me think its the fuelling system since they no longer have chokes.

N.B I know very little about engines so this is a (poorly) educated guess!
