HELP!!! NEW CAR!!! NEW CODES!!!

[PunjabP]

I just bought this 97 maxima... I don't know a ton

HOWEVER!!! i previously owned an 03 sentra spec-v SE-R and added many bolt ons myself

NOW!!! i have read the codes in my car...
0304 _ knock sensor
0401 _ Air intake temperature sensor
0503 _ Front right O2 sensor
0111 _ EVAP control system (flow)

the man i bought this from has put on an air intake himself doesn't seem to be any main brand
but then again he put it on himself

I need to know if i can do any simple fixes? If its just that he never reset the ECU after he aded the intake?
or if i need to get a new O2 or knock sensor?!?!

HELP HELP HELP!!!

Hmm. Interesting question. I might be wrong, but just putting on an aftermarket intake should not cause your ECU to start throwing codes and should not require any sort of reset or tune.

Does the car run rough?
