Fuel injector question

[DontoMelbo]

Thanks for the replies guys. I have replaced the stock plugs twice. I've swapped coil packs. I've used system cleaner and valve cleaner. I still am receiving little misfires once I accelerate to 3kRPM.

After the system cleaner, it ran surprisingly SUPER WELL. But 3 days later it's showing signs again.

I REALLY REALLY WANT A WALNUT BLASTING done to my car. But can't find a single shop that does it. And Ford doesn't do valve cleanings.

Does anyone in Southern California, know of any shop that does ecoboost mustang walnut blasting?

I'm 100% that would solve this problem.

See if this shop will do it for you, they do BWM's. Might be able to convince them that this could be a future revenue stream...
