are you there?

Customer: Here's a little history on what happened. Yesterday I filled up my tank on the way home and after about 3 street lights the engine started shaking while I'm at the light. I get home and go to the auto parts store and they ran a little engine light check with their handheld diagnostic thingy. It should just cylinder 5 misfire so this morning I changed all six but the problem persisted. Anything else it could be?
Customer: Sorry I'm chatting from my cell phone. I feel the shakes and it struggles/shakes hard when I get near 60mph or more
