So upon getting everything else together, all the sensors hooked back up we turned the key and she started right up, then i heard a weird sound... started sounding like metal expanding, so i looked under the truck to find the catalytic converter building up with pressure inside to the point that it was expanding rapidly. I grabbed a drill real quick and before i could get the bit all the way in it had so much pressure that it blew the bit out. so then i drilled more holes and low and behold she runs perfect now, just sounds like a hurricane coming down the road. one big battle over....my wife better appreciate all the work i have put in to this ****ing truck. Now to fix the small things and she will be rolling down the road in a matter of days.
