3500 rpm idle. need help
Ok. A little history first. I did the mod where you remove the boxes attached to the intake tube and replace them with PVC pipe caps.
A week ago I went to Silver Lake Dunes and played. While I was driving home on the expressway, I accelerated to pass a slow car and as soon as I put the petal to the metal, my truck sputtered and died. I pulled over and found my intake had sucked one of the PVC caps in. I fixed it and continued home. But when I got off the highway and slowed for the traffic light I found my truck was idling at 3500 RPM. So that's where I'm at. My 96 4Runner idles at 3500 RPM no matter what. I took it apart today and cleaned everything. MAF, TB etc... I was thinking maybe when my throttle was wide open and it sucked in the PVC plug at warp speed it bent my butterfly valve in the TB. I looked at it and this is what I found. It looks like my butterfly has shifted in/ down. There is a gap in the top and it looks like you can see where it has shifted on the shaft. Is this possible? What is the fix if so? New TB?

As long as you can manually rotate the butterfly on the TB without it scraping the chamber, you should be OK.
Take a look for any vacuum hoses you may have missed starting with all of them that come off the upper manifold.
