What’s it all mean?

Hi
Borrowed a friends Carly and did a scan
P0303 cylinder 3 misfire
P0202 injector cylinder2(N31), circuit malfunction
P0201 injector cylinder1(N30), circuit malfunction

P1564 throttle actuator (J338), under voltage during basic setting

and P0206 defrost flap positioning motor (V107)

So sounds a bit daunting, but at least it explains why it’s a bit sluggish:rolleyes:

Thoughts on what it all means? As stated before the car has done low miles and hasn’t been used much before I bought it. It’s also been sat for a week.
I am happy to poke around and try things, but ’modern’ cars are a bit out of my comfort zone so please explain as if talking to a 6 year old.
Thanks Stuart
 
Ok, will try that.
Done a bit more research and it looks like my first thing to check is the earth strap.
Then clean throttle body,( is there a guide to this?), and then plugs and coil packs.
Does that sound reasonable?
 
Earth strap: never a bad thing to do anyway: if it has a covering, peel it back a little bit as sometimes they can fail nearly, but not quite at, the end. Make sure everything is shiny and clean before putting it back on again.

Codes you have don't shout throttle body, but like the earth above, never a bad thing to make sure it looks O.K. and give a clean if required.

Spark plugs unlikely to throw any codes and unless completely knackered, unlikely to be a cure for much. On other hand, if you don't know the history of them, or if there's a suggestion they might not be to the right spec, worth doing at some point.

Coils give all sorts of issues, but usual method is to take a coil from a cylinder with a misfire and move it to one without. If the misfire moves cylinders, the coil's bad. If the misfire stays in same place, coil less likely (although you could do a second swap with a different cylinder again, just to be sure).

Not sure about the injector circuit malfunctions: earths, engine injector loom, individual injector plugs?
