2008 Toyota Sienna Repair Question
Mileage: 79,000 miles.
Had codes for all 6 cylinders misfiring and garage could not get it to repeat and said it was water in the fuel line.
The shop tried all day to recreate the issue and it never did. I drove it back from the shop (Another hour or so with traffic with no issues)...Can anyone explain what that issue is and how I can avoid issues with this in the future. The gargage said it may have been "Water in the fuel line" but I want to be sure. Thank you.

I have never seen water in the fuel to cause over heating.I have seen missfires engine justs dies and wont start etc but not overheating.Why did they say it overheated?
He gave no reason for the overheat and said it may have been an old code, as I have never seen it overheat. My main concern is the misfiring cylinders and the lack of "cause", as my wife tends to take long trips alone and I bought this van because of reliability.
Those wouldnt be old codes because when the check engine light flashes that means there is a major missfire that can damage the cat.So is there a list of the codes it had the exact code numbers not code descriptions?So it hasnt happened since?Also how many miles ago did it happen?It wouldnt hurt to get a good fuel drier and add that to the tank.I have seen water in the gas cause very phatom running issues.
It was likely 60 miles ago...and not has not happened again and hopefully never again. The mechanic did say when he was inspecting the engine at first that, I believe it was an ignition wire was "loose" and he pushed it down so it had a better connection, could this have caused the 6 cylinder misfire??
That has one coil for each spark plug with a connector going to it.so i dont see how one could set codes for every cylinder missfiring.I would get some good fuel drier i recommend the bg products brand i have used it in the past.It works very good you can find it on ebay or call around to shops and see if they carry bg products.Iam not sure what happened i wasnt there to see it after it happened see the actual codes etc.So did it act up for the people that looked at the car?
It never acted up again for the people who tried identifying the issue, the codes were P0300 P0301 P0302 P0303 P0304 P0305 P0306, I don't have the overheat code.
I would try the fuel drier fuel would effect all the cylinders and could be very sparatic.
