help with truck revving

[protrax]

Hi I have a 07 GMC Sierra Denali 6.2 with a volant cai it has recently come up with an ecm code P0121

So I read I should clean my throttle body So tonight I cleaned the dirty throttle body and put my stock intake on . Now heres the new problem the truck is ideling very high and is revving at like 2000 rpm when it should be ideling I drove it and going down hill with no throttle it wants to do like 50 mph . what the heck do I do now?

Does it have to re learn itself ? Please Help

yes it needs to relearn. you could disconnect battery and reconnect after a few minutes

Sounds like you have an air leak in the intake tract.
