Is this something ill be able to fix my self or dose it have to go to the shop? Yesterday I came here and asked about maybe putting a solution in my radiator cause its blew and is flowing like a river. My toyota isnt working so I had to drive it to the store now the check engine light is on and its flashing. The truck sounds HORRIBLE! It sounds like its drowning. And now its reading a code P0303. I know its cylinder 3 misfiring, but why is misfiring all of the sudden? Is this a major problem? Is it something that a home mechanic could possibly do or will it have to go to some expensive mechanic shop? PLEASE HELP PLEASE!

Start with checking plugs, wire. Chances are that is where the problem is. If you never tuned it up, it is time.
