VERY VERY HIGH idle in heavy traffic

[hoovercjl24]

This is my first post on here, iv been lurking for a while and there seem to be a ton of smart people here which is awesome. Anyways i have a 03 WRX with 30k miles with a catless turbo back exhaust. I also have a lightened pulley, a short ram intake and a BOV .....i know i know, it came with the car. I have never had any sort of problems since i got the car in october until now. I just put the turbo back on 2 weeks ago and have not yet done the CEL fixes.

Well anyways, i was on to the indians game last night with a couple of my friends, and as with any sports events, its stop and go traffic on the highway for about 20 minutes. Well while in this stop and go traffic, my idle continued to rise and rise, by the time i was to my parking it was idling at 5k rpm!!!. I oviously wouldnt let it stay there, any time i was at a stop i would turn the car off. finally got parked opened the hood and it was very hot under there, seemed to be coming from the tranny but im not positive. The temperature gauge was completely normal during all of this and the car drove otherwise normal. I came back out after the game to go home, started it up and it was perfect again. Drove home with no problems. What is causing this and what do i need to do so it doesnt happen again? Thanks

Take off CAI and BOV for eleventy billionth time. Then see what happens.

Blow off valves have been well known to mess up idling. Get a stock BPV quick.

The intake and BOV don't seem to be the cause of your problem due to the fact that it started long after you have had these things on and have driven it. Of course they aren't the best thing to have but I don't think they are the cause to your problem.

Take it to a mechanic not enough information to diagnose.

Check your throttle cable for free movement, and check the throttle butterfly for free movement. I've also seen foreign objects caught in a throttle butterfly after a car was worked on.

An extreme vacuum leak can also affect idle.

BOVs sometimes cause a stumble at idle or off throttle situations. That doesn't apply here.
