DTC 35: '94 Silverado, warm idle only
#1
![Default](/forum/images/icons/icon1.gif)
First off, hello all.
I'm hoping you could give me a little insight on a problem I've got. For a while now I've been getting DTC 35 on a warm idle, which is an idle air control error. I replaced the valve itself, but that didn't solve the problem. The light only comes on when the car is warmed up and idling. If the engine is cold, it doesn't come on, in fact I had it idling for more than 15 minutes a few days ago (cleaning snow off..) and the light never came on. Idle is not rough or anything, and I don't have a tach, but it's not noticeably high or low, though it is possible it is a touch high. Frankly, if the light weren't coming on I would not expect anything was amiss. I haven't noticed any vaccum leaks, though I may look at that again. I've found some people with similar issues, but most involve an obvious idle problem of some kind.
Anyway, thanks in advance.
