Spark plugs moving?!

[SaphSeatIbiza]

Hey there I have a 6J 2015 seat Ibiza TSI, had a new change currently fitted had issues ever since. Worked out EPC And engine light comes on and it misfires and loses power, it drives fine few a month then it happens again. Worked out number 2 spark plug keeps popping out on it own?! And I’ve had it pushed back in twice nice and it’s been fine no doubt in a month it’ll happen again?! Has anyone experienced this? Or has managed to fix it?! The garage(dodgy and took advantage of me) put in cheap £10 spark plugs at first then I said put in Bosch. Still having this issue, would anyone recommend a new expensive set? Or is there another way to keep the spark plug in? many thanks!!!

Have they damaged the thread?

What’s the thread?? They all clip in as I push them in, but the one every so often just pops out!

The spark plug is screwed into the cylinder head, the HT lead clips onto the plug.

My bad they are ignition cables, one of them keeps popping out

You should be able to use a screwdriver or similar to adjust the metal clip inside the ignition lead. If you look inside one of the caps that fits ok, you should be able to see the difference between that one and the one that keeps popping off.

DON'T MIX UP THE LEADS! Number them with paint if needed. If that doesn't work then i'd just buy a new set of leads from the likes of GSF or Eurocarparts etc. As long as you remember to make sure you replace them in the correct order, should be an easy job.
