k here is my problem. I have a Y7 with Y8im, it has been working fine until yesterday. Well actually the car had been sitting on 4 jackstand for the past 2 weeks while I got my wheels re finished. In that time I cleaned the filter on my CAI and I changed the oil Nothing else. I turned the car on yesterday after I got my wheels back and took it around town to run some errands. after I let it sit and idel for about 10 minutes it started idling weird It would go up and down from 1000 to 2000 rpm I didn't think anything of it and I left thinking It will problem fix it self. Later on the CEL came on, I got home and re-set the the ecu and that took care of it temporarily. I then went out again and it later started doing the same. I checked the fault code and it came back 14, it was something to to with the IAC. My question is, do these things normally go bad? I'm going to clean it as it says on the manual but what are my options? Thanks for your time and have a great day.

 

so clean it.............

 

iac's usually dont go bad, clean it and reset the ecu

 

Cleaning it seem to do the trick. It's ideling good and no CEL.

 

ive got a b16a2 swap from d16y8 and my iac code is up and the idle jerks right around 1500ish and on the road there is no even idle its either faster or slower any ideas?

 

if cleaning it is the answer.. how do you do that?

 

Take it off and clean the screen, most times it is full with gunky oil. While it is off give it a good shake, does it rattle? If it does the spring valve in there is broke. If you just flushed the coolant, bleed it.

 

the filter was fine and there was no rattle. whats next?

 

anyone?

 

im lonely here
