I am having a problem with my 2005 Avalon. About 2 weeks ago the check engine light came on and the engine started to misfire. I put some fuel treatment in the tank, I thought maybe it was a problem with some bad gas or water in the tank. I had the check engine codes checked they were P0302, P0303, P0304, P0305, P0306, P0355. The car has about 99K miles on it.
