Bad miss after rebuild Options

[bigjiggy81]

I have a bad miss after the rebuild i just got done, the car just stutters and shakes like crazy and will not basically move anywhere whenever i give it gas, the rpm's SLOWLY move up and the car slowly accelerates but nothing like it should, i changed my plugs, debating on changing the wires still, i am getting 2 check engine codes, like code 13 for intake air temp sensor and code 43 i want to say, i know its the code for the fuel pump, or fuel pump relay, have any of you guys ever ran into either of these codes? its a 90 tsi awd, like i said though the car is missing like crazy and acts almost as if its running on just 3 cylinders, what do you guys think?
thanks a ton

If the iat sensor is bad on the MAF it will throw the ECU into limp mode aka no power mode. I'd check for loose wires in and around the MAF. I have a 1G MAF I can sell you if you find you need a new one.
