Hello all! I have a 2006 SE 3.0 L V6... My issues started with an odd sputter while in park. Things got worse on the way home and the check engine light came on (wouldn't go above 40, shaking, etc...). The codes read multiple misfires on 4,5,6. We were told it was probably the PCM (apparently this model is notorious for PCM issues) so we took it to a shop and after 3 months of them working on it we called and they told us there was nothing wrong with the PCM and we should come pick it up, Also, the coils were not wet or dirty and seemed to have no cracking when we checked them. After putting the PCM back on, we started it to see if anything might have changed. At this point the check engine light was no longer on but the problems were still there. We also noticed that there was a loud knocking in the left side of the intake manifold. It sounded like something was loose. We removed the intake manifold and you could hear something rattle around that my husband could barely feel with his finger. The gaskets seemed in great condition. So......... I am having problems finding any information about that specific intake manifold and/or schematics for it (to try and figure out what was rattling). We are just trying to figure things out and would appreciate any and all info to help with any of the issues. My husband says I need more help than that LOL. We are just ready to pull our hair out and if money wasn't an issues, we would just bring it to the shop. THANKS!!!!
