If the old spark plugs had fallen apart a little bit and the remains

[Sometimes1needhelp2]

are in the spark plug hole itself with new spark plugs put in it is the porcelain glass pieces will this cause performance issues or bad mpg ? Thanks.

Porcelain? OOPS!

The ceramic might pose a problem - plugs have a ceramic insulator - so if pieces of that "glass insulator" fell into the cylinder, then you might have a problem - it usually will "grind up" but the sediment glass will still be in the system and the oil.

So it can run, but it might mean a short interval for the next oil change and if possible a snake camera to view the cylinder piston and walls to compare it with another known clean cylinder to compare for damage if any.

That porcelain is silica - so it's basically a sand - or grit found in Sand-paper - so small amount? Even then requires a disassembly (pull out those plugs) and vacuum it out if you're not sure - so the particles still in the cylinder can be removed - but if the engine was already driven - then this point is moot.

1 very last thing for now. I would used to be able to lock my doors from the inside while my car engine is running now I cannot I can only lock them while the car engine is off BUT, I can still lock and unlock all door with my regular key not key fob but just the key itself I would so apricate it if someone like you here could give me some button type code. Thank you and take care. This Ford Fiesta SE engine is a VERY WELL MADE engine actually. Very well made.

I have not had many mechanical issues at all with this 2013 Ford Fiesta engine but I do feel like if I could remove the remaining spark plug debris that will give me better mpg and here and there my vehicle does take a little time to get up and go at time but very rarely.

I never use a regular 5/8 spark plug socket on plugs in twin cam engines. There is a extended length version of socket for getting the plugs out/in without breaking the insulators. It's worth every penny of it's slightly greater cost. Especially since double platinum or iridium plugs are so expensive.
In the rare occasions I find bits of insulator in the plug galleys of twin cam engines, i take a McDonald's drink straw and a bit of freshly chewed bubblegum to dive in and grab the chunks.
