Every once in a while, I'll find it idles high, like 1500rpm compared to the normal 750-800. Some times it does this right off start up, some times it does it while driving / in between shifts (if I hold it in neutral for a while), or at stop lights. Some times it goes away on its own, some times I can load up the engine some and force it down and it stays, and some times I have to cycle the car off / on and it goes back to normal.

As I changed 3 things at once (TB, CAI, EC Tune), I can't say for sure what the actual issue is. I doubt the CAI did it, unless I screwed something up with the MAF and it's causing an issue.

Any thoughts?

I am having a very similar issue and ive replaced my breather hoses, quadruple checked all for any leaks, replaced o ring on tb, replaced map sensor, tried a new accelerator peddle assembly. All that's left is a new TB that I can think of unless somehow the valve covers can cause a vacuum leak. I just ordered a new 74mm tb, I put a used on one a year ago and hoping it just went bad after this. My idle just started t hover around 1700, but only sometimes, other times it would be normal, other times it would rev up and down, and sometimes if i rev it it will just stay at a high idle. Was the TB your issue?
