A week ago i bought this car and the only error code on it at the time was a p1504 for faulty idle air control valve. the car would stall at redlights and stopsigns, so i took care of it. the car no longer stalls but now it has a check engine light on with a bunch of different codes all pretty much saying lean or rich fuel mixture, and it cant adjust the trim in both banks. the codes showed up before i replaced the iac valve and i havent cleared them yet. could a faulty iac valve cause these codes or should i look elsewhere like the map sensor?
