CEL after UIC pip install

[dope96clipse]

ok heres the deal, i broke the stock UIC pipe so i fab'd a 2 1/4 inch D, pipe an installed it instead, well when i started the car up it idled fine but when u give it gas it would stall out, but after like 5 min it was all good i think the ecu was learning b/c of the better air flow , but now i have a CEL an a odd knocking noise everyonce in a while while driving if i reset the ecu i comes back after like 5 or 6 min, oh ya an both my fans turn on the second the car does an it doesnt turn off, i will post pix in a few i have to take them n capture them i wanted to see wut ne one thought it was cuz im lost

Go to autozone and get the code pulled (its free), otherwise I have no way of knowing what the problem is, maybe some type of sensor got ####ed up (just a guess)?
