Hi Folks, Elvis did a stutter or stumble today. I filled the tank full, and right afterwards felt a stutter or stumble. At the next light I got on it and it stuttered its way up the rev range. Then it cleared up. Hasn't done it since. Amoco 93 octane. I topped up the tank. Could that cause a stumble briefly? I was also thinking water in the gas? If it had a misfire, would it have thrown a code? That is why I was thinking water in the gas, and yes, it has been a rainy and damp day. Anyone else had something similar? Many thanks and God Bless, Marc
