Hey guys sorry i havent been on in a while(computer was down) and havent been doing anything but working on my money pit truck or working at my job.

But heres the update on the my dakota. I ended up having a blown head gasket and cracked heads. So i replaced both heads and all new gaskets later....it is running way better now. I still get the hissing on cold starts from time to time and it runs rough when it hisses which is weird so im not thinking its just the top hat intake causing it. It reacts like a vaccum leak but the idle dosnt surge it stays solid but the engine hemies for a couple seconds and then it subsides and it runs fine after that. Im pretty much lost on this one im thinking it is the iac but ive replaced it with 2 different new ones to no avail so far. If anyone has any ideas on my dakota that seems to want to be a snake for some reason. It would be greatly appreciated. Thanks!

Heres the specs on my truck btw. 00 dakota sport 4x4 3.9l manual trans.
