    My brand new V6, manual tacoma has been misfiring. When I took it in they told me that the #1 coil had backed out and it was a simple repair. The truck was running great again for a week then it started to have the same problem. I brought it back in and they replaced the #1 coil. However, it is still having a misfiring issue. They seem to think that there is water in the gas and that the water has been causing the coil to back out. They want to pull the engine apart and clean it up to get the water out. An engine tear down isn't covered in my warranty and I don't think that pulling the engine apart is going to accomplish anything anyways. Anybody have any ideas as to what the problem could be?

    The car has less than 5k miles on it.

    I'd go get a second opinion. I don't see the need to tear the engine down, if there's water in the fuel. That doesn't even make sense.

    Yep, go to another deal If that doesn't do it call the national toyota customer service line. The last thing they want is a lemon out there.

    Sounds like the plug might be having some "blow-by", causeing the coil to pop off the plug.....

    Thanks for the replies. I wasn't buying the water story either.
