This may not be the same thing, but this is what my problem was. I mixed up #1 and #2. Idle was high all the time. I put on hose clamps on everything and was checking for leaks everywhere. Then just sat back and looked at it and realized what I did.
Hope this helps.
Yes fellas I mixed up one and two. The RPMs go through the roof and if you give it gas thinking it will settle, it wont. It will get stuck at a higher RPM.
