wont idle up?

hi guys i noticed these past few chilly mornings that my truck no longer idels up in the morning. The temps have been in the 30's at night with a few nights of frost. just wondering what would cause this not to work. Oh and the ebpv doesnt kick in either. Thanks

My new 2000 hasn't idled up yet either, my ebpv does kick in though. I remember my 01 would have to be colder before the high idle would kick in. Your ebpv sensor could be shot or the valve might be sticking. There is also a tube that connects the sensor to the pass side exhaust manifold. That can get clogged with soot over time. Usually though the problem is the ebpv sticking on for people. Just check out some of those things.

Thanks Dieseldan, I will check that tube and put a new sensor in, as i have one in another motor.

check that sensor with a scan tool if you can before you replace it. They aren't that cheap. I bought one on ebay a few yrs ago for $65 but normally they run over $100 i think. Just so you don't waste any money.
