Please can anyone point me in the right direction on the best fuel injector cleaner I could use. I have the P0304 diagnosed on my car, swapped coil #4 for #6, cleared the code. After about 5 days the CEL and Check VSC came back on again. On doing the diagnostics again, it still came back with P0304, which was an indication it was not faulty coil #4, car is just 15k miles, therefore eliminated spark plug problem, no hose unplugged in the car, and no broken cable. I was told it could be the fuel injector.

Therefore, I was advised to use the fuel injector cleaner, can anyone advise on this? I am open to all solutions. Thanks

I would still replace the spark plug in #4 (or move it to another bank to confirm) and also clean the injectors. For cleaning I usually use Sea Foam treatment...

I prefer Redline fuel injector cleaner. It has the most detergents than most of the other fuel injector cleaner brands.
