I'm not sure what the code was that came up. The fit told me it and of course I don't remember. I just tried taking the new one off and putting the old one on. Ran the way it used to. Rough and low idle wanting to stall. I put the new one on and it was fine. I let it run for a lil and it made the sound where it was running rough and gonna stall. Could the throttle body might have to be cleaned?
