Just got done rebuild top end of my 4.7 magnum after a blown head gasket. Got everything back on there. Got the heads machined and all new gaskets. It idles fine but when you give it good amount of gas it wi’ll bog(jerk forwards a bunch until you let off gas). it was also throwing a code, it was for a cam position sensor, replaced it and it drove find them after a drive started doing it again. I wiggled it around and drove it again and it drove fine for a little, so I put some of the metal paste that comes with the sensor in the whole on the plug for the sensor and it drove fine. Then this morning started doing it again. Anyone have any suggestions. i’m thinking the plug isn’t getting a good connection so it needs more of the paste but I been working at it for a month now and am open to suggestions.

 

I'm assuming you've got it figured out by now, but, you're not supposed to mill the 4.7's heads more than 0.002", it causes cam timing issues. I'm not exactly sure why it does, but I can guess it's due to the sensor getting closer to the gear as a result of milling it. I hope this helps, that is, if you haven't figured it out by now.
