Doing this in the yard with engine flusher on.
Engine cranks fine. Idles fine. Rev it up it sputters then clears up at 4000 rpm.
Bring it back to idle it runs really ruff for about 3 seconds and cuts off.
Turn the key off and back on restart the engine it idles fine again
Rinse and repeat same problem every time
