3.4 swap bogs like crazy

3.4 swap bogs like crazy
I just got the swap mostly finished, but when I give it some throttle it bogs at first then revs up(this is when parked). When I am driving(under load) if I give it more than a feathering of throttle it will just bog and never come out of it until I let off of the gas. I flipped my MAS incase I had it in backwards and unpluged it and it seemed to be doing the same thing. It had no codes until I unplugged the MAS. I am also running the stock 3.0 exhaust setup with the 2nd O2 sensor installed, would the stock exhaust create to much back pressure, could this be my problem?
Any help would be great thanks.

Okay lets trouble shoot..
Make sure all the grounds are the motor are completed.. If you are missing some grounds then it will not run properly.
I would check there first, you need all the sensors hooked up as well.

I can't see any disconnected ground, off the top of my head I can think of 3 that are connected. I pulled the motor and trany out of a crashed donor, so I left everything plugged into the motor and pulled the wiring harnes out of the fire wall. I also have 2 more questions. Does the fuel pump run constantly on these or should it cycle when it pressures up? And since I put the new M/T in place of my A/T is there some more sensors I need to get from my donor? And I just cut the engine/body harness for the body harness plug, what all should I need to run back into that?

The igniter from my donor was destroyed so I got one on ebay. Are most 6 cyl igniters compatible around this year? I ask because a few of the wires were different colors, but I used my EWD from techinfo.com and the igniter was labeled.

I was looking at radio shack's site and they have a few types of 10k ohm resistors that vary by wattage(1/4w,1/8w, 1/2w). So does the wattage not matter, because I can't find any info?

I think I found the original problem. I didn't have the wire hooked up that powers alot of the sensors. But now I have a different problem. It is hard to start when it is cold, it backfires and has no power, it has more power in low RPM's and revs very slow over 3000 RPM.

Has anyone ever had proplems with pulling codes from the ECU? They kept on getting a error when I tried to get them. I checked and rechecked my plug wires and they are hooked up right.

I have also experienced that issue. I'm going to the shop today again to try and get some codes... My 3.4 isn't even starting right now and the spark plugs are black and soaked...
