you should have come here before you spent all of that money on changing all of those parts. first of all dont Chang anything else until you check it out and see it is bad it only complicates things.
Did you check each of the new components that you put on? dont assume that just because it is new that it will work perfect.
what engine are you working on and what year and transmission? cant help you with out that info.
check all of your vacuum lines and elect. connections and one time more for codes.
get back to us with that info and we will figure it out.

OK then you have gone through hell already so we need to get this thing going.
you said it idles fine for like 1 min then bogs and spits spuders for like 1 min then it is fine.
OK it should idle fast and then kick down at about 1 min. and again in about 1 min. so during the second min. is where the problem is and then it straitens out .
Can you check to see if the EGR is opining during this time? also it would be good info if you could put a timing light on it and see what the computer is doing with your timing at this 1 min time.
get back on here when you have that info and I am going to crack some books on this tonight.

it would also be good to note anything else that is going on at that time such as the smell of the exhaust. to determine if it is running rich or lean for that one minute of time.
the computer runes through a series of routines on start up and these will vary according to the conditions. and your computer is doing something at a certain point in the warm up that is either callusing the problem or it is receiving information that is causing it do make a chaging at the wrong time. it is our job to find out what is going on so we can fix it

Every sensor, every wire and every part of the vacuum system and still no red flag...
How did you do all this testing and what kind of tools and equipment did you use to do all of this testing??
Is this a mass airflow system or speed density??
