Fault codes on my ibiza cupra

[ReadieeVTS]

Hi guys got some fault codes on my ibiza cupra AQX engine;

P1361 Cyl. 3, ignition circuit Open Circuit
P1128 Long Term Fuel Trim mult.,Bank1 System too Lean


The car will boost fine for about 15, 20 miles and then it will go into limp mode, fuel consumption is pretty bad too. I've tried unplugging the maf and see if it runs better And it doesn't it runs worse and wants to stall alot so it can't be the maf? I've replaced the precat lambda too. Any idea guys its burning a hole in my pocket

wiring to coil on cylinder 3....
does the fault travel if you swap coil over?

Well I've got rid of the p1361 code, was the nasty Bremi coil pack I had which was brand spankers may I add, so keep away from that brand people, I also noticed that a few vacuum lines were looking old and tired so renewed them and haven't had a the fault come back.... YET so will run it for a few days and see how she goes..
