RE: P0404 code and bad running
O.k., to give an update on this problem, after about 4 hours staring at the factory manual.... I found it, not much mention like you said. Anyhow, pulled it off and it looks to be fine. Now, with that being said, it has alot of carbon caked on the inside. Not too much though, just enough to get my wonders going. So I am cleaning it out with some carb cleaner and putting it back in.... We'll see what the outcome is. Also, I had the Bosch Platinum +4 in the engine. Decided to pull them out just to look, since the tech at the dealer said that the Hemi doesn't like plat...... Anyway, they were blacker than any plug I have ever pulled from an engine. Maybe thats a contributing factor???? Thanks again for the info, will send back when I am done with this and update as such.
