    I have to say last summer i had a little trouble with my temp sensor and it threw a code every-time i cranked her up, and the electric fan would stay on all the time. I believe it's something simple what-ever it is....

    It could be the coil pack but probably is'nt. My 2000 did this and i changed the coil pack and tried a new ECU. Neither solved the issue so I ended up taking off my fuel rail and pulling the injectors. Turned out my fuel rail was so full of crud # 5 and 6 cylinders couldnt get fuel. Cleaned everything out and everything was good.
