My CEL and egr code just started randomly started poping up.It hasnt ever done this before, has this happened to anyone. maybe one of my solder connections came loose. Any opinions?

I'd say check connections and if they are fine than i havn't a clue maybe it got soaked, i dont know.

Whats the code? If its P0403 is an indication of a problem with the servo motor electronics and is unlelated to the finger stick witch will neither cause nor cure this code.
P0402 It is likely that you have an aftermarket air intake. Try switching back to the OE intake. This will likely cure it.
P0101 This indicated a problem with the installation or the stick. In short, it isn’t working at all.
P0401 and/or P0404 The problem is the Stick is not modifying the signal from the MAF sensor. The most common reason is the customer is into the wrong wire(s) in the harness. You must trace the wires back to their connectors to be sure you are into the correct wire as outlined in the instructions. The next most common problem is the customer has not cut into the MAF signal wire, only tapped into it.
