Random idle/neutral Missfire

[Vapor2.3]

Hi
I've been chasing this problem for awhile trying to get my car tuned

I have a 2015 2.3L mustang

I've already replaced my spark plugs and gapped them to .026
I've replaced my coil packs
I've replaced my low pres fuel sensor
I've cleaned my air filter
I've also replaced my purge valve
And I don't have a head gasket leak because my coolant level hasn't dropped

I don't really know what else to check or do I don't have the money to keep replacing part and sensors

If anyone has any other forums who solved this issue or have a fix for it that would be greatly appreciated

I'm just trying to solve this so I can finish my tune

What's your codes? Replacing parts without knowing any codes is throwing money away.

Have you checked:
- Make sure all grounds are secured
- there isn't any vacuum leaks or breaches to air intake system
- make sure all connectors to harnesses are secure and not loose
- fuel psi

Also what do you mean by "so you can finish your tune" - what exactly are you doing from a tune perspective and what tune is it?

All my grounds are good to my knowledge I'm gonna run some CRC cleaner to clean my valves from carbon buildup
I'm also gonna check for vacuum leaks at the same time
I'm not sure what my fuel pressure is but I can check that

And I'm getting a tune done by Adam tune on 91 pump gas

And I have no engine codes
