So I unplugged the MAP sensor and it ran great, will be replacing that soon. Although after that it caused the ETC light to come on and throw a P2106 code. Another thing I noticed that was not on my original heads, on the passenger side, front of the cylinder head there is a hole with a rubber grommet in it. It has a hole on each side of it for bolts to go into, unlike the original with only the one hole. I have a picture but I'm not sure how to post it. Any ideas?? When I plug the hole with my finger all the engine noise that was heard in that video is gone and it sounds like a normal truck again. THanks,

 

Nevermind......... EGR block off plate needed.. guessing this didn't come out of a Ram

 

No, it probably did, the newer years, I think starting in 04', came with an EGR valve. I cant remeber if the 03's did or not but since you said that yours didn't have one then probably not. In ancase that year engine was meant to have one

 

so is it bad if I blocked it off??

 

No, a lot of guys like to block off the EGR to keep it from recirculating hot exh back into the heads

 

I new I heard an exhaust leak in the video. It was the open EGR hole.

 

yeah it sure was.. Sounds much bette now.. Didn't even think to check that
