i was driving my daily driver yester day and the throttle stuck at 2500 the i got out and moved the cable and moved the butterfly worked fine for a couple of miles then it stuck wide open again. when i got it home there was ice on top of the butterfly and almost like condensed water in the manifold with a little oil. I checked the water pump and radiator line so on and so forth but nothing seems 2 be wrong it blew a little oil up threw the intake and intake lines but its all mixed with water. the head gasket isnt blown either. only thing i can think of is that there is a leak some where could u guys help me?
coolant passages in the intake manifold blocked? The coolant warms the t/b to prevent icing
If you got it, a BIG truck brought it!
i dont know i will check them tommorow when i tear everything apart still dosent make sense all that stuff is brand new except the throttle body. obx intake manifold and, aem intake
what i ment 2 say was im checking everything 2 morrow all the hoses around the manifold and in the manifold dont know where all the water is coming from.
when i first read the title, i was like omg no dont put ice in your throttle body.

J's don't have coolant running through the TB (3rd gens don't anyway, and 3rd gens are all that I saw in your profile).
What are the atmospheric conditions where you are? Iced TB's typically only happen in very cold and high humidity conditions when the intake manifold is under a small amount of vacuum (partial throttle like when cruising down the interstate).
The conditions for it to happen are quite rare...Unless you have some other problem going on that is getting moisture to your throttle body some other way.

Sleeper style, they don't see it coming that way.
it was like 8 degrees out and i was just cruising. but after tearing it down i found that the gasket was missing off the TB to the spacer causing water from all the melting snow to seep through and freeze the butterfly.

one thing to check is your intake filter. You profile says you have an AEM intake. When i ran mine in winter it would let fine snow particles thru and then it would freeze things up just like yours. IMO if your still running an AEM filter you should scrap it for a better one.
thanks sleepy its already scrapped i have a spectre racing cotton ram filter on it now. never like AEM filters either
anyone see the irony that cryo skull posted about icing problems?
i only posted 2 see if anyone knew what it was before i had 2 tear it apart thanks sorry i waisted a post on this

Our cars don't have coolant running in the intake manifold or throttle body.
lol to the fact that this even needed to be stated!

I only know this to be a fact for 3rd gens. 2nd gens may very well have coolant running through the TB. My Fiero (2.8 v6 -- although it's a gen1 2.8 and not the gen 2 2.8 that cavvies got, so it may not be a valid comparo) had coolant running through the TB (I bypassed it because it is not necessary, and a PITA to deal with when fiddling w/ the top end).
So, while an invalid concern for a 3rd gen J, it was not an invalid question, as it was something that GM (and probably others) has done in the past (and may still do on some models, IDK).
