Random intermittent Cylinder Misfire code (on phereable 1.5 tune)

[ghst 25]

Hello, haven’t been on here in a while but I’ve been having this weird issue where I have a cyl misfire code (It’s usually cyl 2) after every like 5-9 cold start ups. I put new spark plugs in and that did not fix the issue. I swapped coil packs around and still stayed on the same cyl. I’ve heard all the noise about it being a head gasket but have seen any signs of coolant loss or anything of the sort. There was a guy on here who had the same issue and I was wondering if he ever found the fix for it? It’s sounds like it needs a new fuel injector but after looking on here I’m not too sure. I’ve included pictures of the old plugs, the coil packs and the code. All help is welcome.

Curious.. Do you have early spool turned on or off in the software?

Honestly I have no idea how to even check that.

When you get the tune file you use the ktuner software to load the tune on your ktuner device. In the software you can change 2 settings - early spool toggle and auto-start/stop disable.

For fuel injector you could add stft and ltft to your ktuner display. If ltft is -10 to -20%, it might be the fuel injector. Stft and ltft typically bounce between 0% and +/- 1-4% when healthy.
