Hesitanting on start?

[Hypergram]

The last week or so I've noticed my car is hesitating to start, both hot and cold starts (but is worse on cold starts) and I was wondering if I could get any ideas why or how to fix it? 2018, 10,000 miles. I also have a Dizzytune if you think it makes a difference.

What was the last thing that you did before it started acting up? Go from there , it's just a process of elimination.

Did you change the spark plugs? If so, I'd check the gap

Overfill at the pump?

Overfill at the pump?

This. Our cars have a tendency of not liking when you top them off. There's also some issues with the evap system that can cause a stutter at times, which can be prevented by not overfilling and inserting and removing the nozzle a few times before after you're done filling up.

Last thing would be the intercooler. You think that would make a difference?

I did change them about a month ago. They were pregapped by Ron for the specifics from Dizzy. It was fine when I installed them.

Nope. happens on all sorts of fuel levels.

Yeah I'm aware of the evap issues. And I never overfill and follow all these steps. I don't think this is the issue since it's only on start ups?

Dizzy knows what their tune needs, however, I noticed cold starts becoming and "issue" with 1 step colder. I'd check the heat range and go from there.

So I don't mean to be a harbinger of doom but:

I went through this with me 2016, I had about 15k miles when it started to happen and I would just change the plugs out to make it go away. But it would come back. After the 3rd set of plugs in 10k miles I started to get suspicious, so I was pulling the plugs out and my #2 was stuck in the head. Long story short, Ford replaced the engine. There is a well known issue with coolant intrusion into our engines but you mainly see it in the escapes and fusions, Ford will just replace your engine if you are under warranty. You can find out if you have coolant intrusion by removing your spark plugs and inspecting the cylinder for coolant / wetness. My #2 was very wet when I finally got the plug out and the plug had rusted to the head.

Yikes... This sounds pretty shitty considering I have a tune... I'm getting my 10,000 mile service sometime soon, I'll bring this up to them and I'll check my plugs ahead of time. Thank you.

Do you have a link or something for me to get more information on this? I remember there being an issue with their earlier 1.6 litre turbos, but I thought it was fixed before yeh 2018s And do you think me having a tune will produce warranty complications?

I don't have access to the Ford database anymore, but it should be in there. However it would be under the Escape 1.6 not the Fiesta ST. I was full bolt on, stage 3, pro-tuned and i just put it back to stock and played real dumb at the dealer. They didn't ask questions.

This... I'm at 45k and have been through two sets of 1 step colder plugs. The hesitation is almost non-existent when first installed but gets worse as the plugs age. She starts up every time tho. Just some days she wants 2 or 3 more cranks. For the record, i don't have any signs of coolant intrusion.

Mine did the same. Sometimes it would take forever to start. I think if you drive it hard enough, you burn it all out but otherwise (I babied that car) it sits and collects.

Just remember to flash back to stock before taking it in and in fact if you flash it back now and try to start it a few times as stock and see how it is wouldn't hurt to get ignition cycle count up from 0-1 as if you flashed *right* before taking it in, if you do...

Yeah I was thinking about it earlier. Good idea thanks.

Ok so I flashed back to a stock tune, should I uninstall the Accessport right now too?

Update. I took out the Colder plugs and swapped back to the OEM ones (thankfully I kept them). I didn't see any coolant during the process, but I did see what looked like a little dirt. See attached. Any ideas? Also it seems to be starting a bit more smoothly.
